1.Q:Can
customer use Generator as AC source to connect with inverter?
A:
.As we know, generator always supplies unstable
power and surge power of generator is very big.
So, we don’t
suggest customer to use generator as AC source.
2.Q:
Please kindly recommend solar system to us.
A:
We need to know following information and then can recommend suitable solar
system for you:
1) Please kindly advice if you need stand-alone solar system or grid-tied solar
system.
2) Total wattage of your appliances
3) How many hours a day you will run your appliances
4) Do you have mains power? How long the mains power will supply?
5) The daytime for sunshine
6) Will you use a generator with your solar system? If so, please kindly give us
the spec. of your generator.
3.Q:
Why we can’t use Modified Sine Wave Inverter to run
FLUORESCENT LAMPS?
A:
Because the fluorescent lamp with power
factor capacitor,
the main function for power factor capacitor of fluorescent lamp is
to
enhance the AC power efficiency in Pure sine Wave inverter, not Modified Sine
Wave Inverter. So it will cause the opposite
effect
if customer uses our modified sine wave inverter to supply power to fluorescent lamp. Furthermore,
it will cause the high
voltage
MOS.of our Modified Sine Wave Inverter get a short cut.
4.
Q: Can we connect two same specification inverters to increase the output power
wattage?
A:
Normally, the inverter is not a stackable inverter. Customer cant connect two
inverters in
parallel for double the output power.
This inverter only
can use separately.If
customer need a stackable inverter, please visit our website (www.kipoint.com.tw)
to
find our SI
stackable inverter.
5
Q: For PLC and PSLC series inverter, the description
says: Multi-stage charger supports batteries up
to 600AH.
If
I have battery more than 600AH,can we use it?
A:
Although the max.charging current is set at 600amp hours. However, customer
still
can use our inverter with built in battery charger
to
charge more than 600AH batteries bank.
The
difference is that it will take more time to charge more than 600AH batteries
bank by our inverter with built in battery charger.
For example, customer uses our inverter with built in 50 amp battery charger to
charge 600 AH battery or 1200 AH battery.
The
charge time as below.
1) 600AH battery divide 50 amps battery charger: it will take about 12 hours or
charge battery.
2) 1200AH battery divide 50 amps battery charger: it will take about 24 hours or
charge battery.
6.Q:
Can we use external battery charger or solar controller to combine inverter with
built
in battery charger or
solar
controller for charging battery?
A:
Customer can’t use external battery charger or solar controller to combine our
inverter
with
built in battery charger
or solar controller for charging battery because the charging
current and voltage of each charger all different.
It will cause
inverter get damaged if customer combine to use.
7.Q:
Can we use battery charger to charge Gel
or AGM battery?
A:
Yes, for
Gel and AGM battery all belong to Lead Acid battery. So our battery charger
can suitable no problem.
8.Q:
What is HZ ?
A:
It means Output Frequency, It forms several waveforms in each second, or it
makes several
time same movement in each second.
9.
Q: What is difference of CC and EC series Inverter?
A:
The function of CC and EC series Inverter are almost the same .The difference as
below.
CC series: LCD display.
EC series: LED display.
10.
Q: What is difference of
CC and PLC series inverter?
A:
PLC series: applicable
for any kind of loads such as air conditioner, home appliances, consumer
electronic and office equipments.
CC
series: applicable for any kind of loads such as home appliances, consumer
electronic and office equipments.
The
difference of PLC model and CC model is for the inside design of transformer,
the size of built in battery charger and the transfer
time
is also different.
The
max built in battery charger for PLC series inverter is 60 amp.
The
max built in battery charger for CC series inverter is 35 amp.
The
transfer time of PLC series inverter: AC--->DC < 8ms.
The
transfer time of CC series as below:
Blackout
3ms typical
Brownout
1ms typical
Battery
mode to Normal mode:1ms
typical
So
if customer want to use inverter to connect with computer for operation, once AC
mains power fails, it needs to take very short
transfer
time to transfer it from AC to DC battery for back up. Then well suggest that
customer use CC models because CC models
with
short transfer time.
11.Q:
What is difference of L and H series inverter?
A: L series and H series is pure sine wave inverter
only. Due to there is no built in battery charger with these inverter
so L and H series don’t have charger function.
The difference for L and H series inverter as below:
L series inverter with low frequency transformer and it is suitable for
sensitive equipment.
H series inverter with high frequency transformer and it is for normal use. But
H series inverter is with one more by pass function.
H
series inverter can be connected with AC mains power on the input.
When
AC mains power is normal, the inverter will by pass
AC
power to the load. When AC power is cut, it will transfer to get power from
batteries. But H series inverter doesnt have a charger
function. So, if your battery is no power when AC power is cut, the inverter
will be shut off. Hope you can understand our explanation.
12.Q:
Can we use inverter as UPS function? (base on the item of inverter with build in
battery charger)
A:
Yes, this inverter can supply as UPS. When customer use AC mains power to
connect with inverter, the inverter
with build in battery charger will charge battery and by pass power to the load
at the same
time.
Once AC mains power
fails or cut off, it will transfer DC battery power from inverter to the load
used.
13.Q:
Can we use inverter as UPS function? (Base on the item of inverter with build in
battery charger
and solar controller)
A:
Yes, this inverter with built in battery charger and solar controller. At
daytime, you can connect solar panel into this inverter directly.
The built-in solar controller will charge the batteries by solar panel
and supply battery power from inverter to the load.
Besides customer
can use AC mains power to connect with inverter, the inverter with build in
battery charger will charge battery and
by pass power to the load at the same
time. Once AC mains power fails or cut off, it will transfer DC battery power
from inverter
to the load used. Customer
can use battery as a back up in the evening.
14.Q:
Can this inverter can split it into 2-120 lines or use as 3 phase inverter?
A:
Most of our inverters are single-phase inverter, it can’t split into 2-120
lines or use as 3 phase inverter.
15.Q:
Will the battery charger auto to shut down when battery is full charged?
A
: For our charger wont auto to shutdown while LED turn to fully charged. Its
also not necessary.
This is because
lead acid type battery with nature
self-discharged
feature.
So, once LED turn
to fully charged, the charger will transfer its mode from bulk to float.
And has lower
voltage to charge.This
is to compensation battery purpose. Its safe even leave charger on for months
16.Q:For
SLC and LC series inverter, the inverter with built in 40 amp or 50 amp or 60
amp battery charger,
how
we can get the max charge current?
A:
The max charging current is 40
amps or 50 amps or 60 amps, but this is
not continuous charge current.
Moreover, the max charge current will be only achieved in the condition of
the battery is out
of electricity
and also depends on the distance of DC battery cable between battery and inverter.
17.Q:
What is Solar grid-tied system?
A:
Solar Grid Tie System or Grid Connected System is connected to utility grid and
feeds power back into the grid.
The system consists of PV panel connected to grid tie inverter. The power
produced by the PV system can be either supplied to loads
or fed back into grid when the PV system output is greater than the load demand.
When the PV system output is less than
the load demand (e.g. at night), energy will be consumed from the utility grid.
Solar grid tie system varies in size from residential
to solar power stations.
Keep this
in mind: A grid-tie system do not have battery to store the energy and they must
installed where the grid line reachable areas.
Solar Grid-tie systems usually have not battery device to store power. Thus the
costs of establishment and maintain are lower than
these stand alone systems.The
electrical power generates during sunny
days to save power from public utilities and sometime resell to
Power
Company. At night and cloudy, rainy days, the electrical power still comes from
Power Company.
18.Q:
What is Solar stand-alone system?
A:
Stand-alone systems are not connected to the grid. Off-Grid
systems (standalone) use a photovoltaic
system to supply electricity
to a consumer unit
directly or via a battery, independently of other energy sources.
Stand-alone Solar Power
System, Stand-alone PV System or Off-grid
Power System operates independent of the electric
utility grid (off-grid) and most often uses in remote areas
where the utility grid is not available or where the connection fees of
the grid are higher than the cost of an alternative energy system. The generated
DC power needs to be stored in battery
and converted to AC power for supplying to AC loads. Stand-alone Solar
Power System suits to use for remote
village electrification or rural electrification
to provide continuous reliable power at remote locations.
Stand-alone solar
system is suitable for any areas where utility power line is not available.
This system requires
a charge controller to charge storage batteries for discharge to run electrical
appliances.
Stand-alone inverter
systems consists of a standard Solar Home System with solar module, battery and
solar charge controller,
plus an additional
inverter that supplies AC power.
19.Q:Who
will pay import duty?
A:
All our
products and shipping cost do not included VAT.
Regarding
import duty, sometimes customs will inspect the parcel
but sometimes will not. So, we
cant know how much the customs will charge for the inverter.Normally,
we will send the product as gift or sample
and put lower value on invoice to help customer avoid the import duty. We will
do the same way for you.
If you have any special request about the invoice value, please kindly advise us
in advance.
20.Q:Can
we use inverter on appliance with
induction motor,such as air condition or
pump?
A:
As some appliances and tools
with induction motors may require from 3 to 7 times the continuous wattage when
starting.
The
start-up load of the appliance or tool determines whether an inverter has the
capability to power it.
Be
sure to check the specific wattage requirements and operating instructions for
appliances / tools to be used.
So,
please make sure the continuous power wattage and surge power wattage of your appliances
are not over our inverters request.
For
Example, if
your air condition indicated an output of 1200 Watt, the starting current
can be up to 7 times.
This
would mean, that you must select a Power Inverter, which can accept a short term
maximum performance of 8400 Watt.
Please
absolutely pay attention to this important factor and order none to weak
Inverter for your equipment because it could damage
the
inverter and your appliance !
21.Q:For
Stand-Alone Solar System, Why the solar panel power is not enough for
the whole system?
For
example KI-SA-2400,this is 2400W solar system, why only supply with 195W x 6 pcs
solar panel (about 1170W)?Why can’t supply 2400W solar panel with 2400W solar
system?
A: Please
kindly don’t confuse Stand-Alone Solar System with Grid-Tied Solar System.
Grid
Tie Solar System is connected to utility grid and feeds power back
into the grid.
The system consists of PV
panel connected to grid tie inverter. The power produced by the PV system can be
either supplied to loads or fed back into grid.
Customer can complete use
full solar panel power to a Grid-Tied Solar System.
For example, if customer
have a 2000W Grid-Tied Solar System ,then it will be provided full power 2000W
solar panel with inverter for operation.
Take
Note: Grid-tie Solar systems have not battery device to store power.
But for our Stand-Alone
Solar System, The generated DC power needs to be stored in battery and converted
to AC power for supplying to AC loads.
Stand-alone Solar Power System
suits to use for remote village
electrification or
rural electrification to provide continuous reliable power at
remote locations.
Stand-alone solar system is suitable for any areas where
utility power line is not available. This system requires a charge controller to
charge storage batteries for discharge to run electrical appliances.
For
Stand-Alone Solar System,
the max power current of Solar
Panel is what we most concern and solar panel is only related to the charging time, not
about solar panel wattage. The solar panel set only provide charging to the
battery packs instead of providing full power.
Battery
capacity is most important factor for Stand-Alone Solar System and it depends on
how long customer want to run appliance by inverter.
For example KI-SA-2400,this
is 2400W Stand-Alone solar system and inverter with build in 50 amp Solar Controller. So
the max power current of solar panel can’t be over than
50amp.The max power current of 195W solar panel is 7.63AMP/unit. So we only can
supply with 6 pcs 195W solar panel(7.63Amp x 6 pcs=47.78Amp).
If customer want to use
battery to connect with inverter and run full load 2400W(24VDC) for 1 hour, customer
have to select about 24VDC 200AH battery. Since the max power current is 47.78 amp. The
Charging time will be about 5 hours (200AH/47.78 amp).
If customer want to run
appliance longer, customer can connect more batteries bank but it will take
longer charging time.
