1. Thailand
Q1: Can I use this inverter to charge my electric scooter or other
EV batteries?
A: The inverter provides standard AC output, so you can use it to
power an EV charger. However, please ensure the power rating of
your EV charger does not exceed the continuous output rating of the
inverter you choose.
Q2: Is the 120A MPPT on the EM6200 model sufficient for a large
commercial shop?
A: The 120A MPPT is one of the highest in its class, allowing for
very rapid battery charging from a large solar array. This is ideal
for commercial operations with high daytime energy consumption and
battery replenishment needs.
Q3: How does the "Lithium Battery Activation by Utility" feature
work?
A: If a compatible lithium battery enters a protective shutdown mode
(zero voltage), the EM2500 and higher models can use grid power to
"wake up" and initiate charging, providing a crucial recovery
option beyond just solar.
Q4: I have a lot of inductive loads like water pumps. Can it handle
the startup surge?
A: Yes. The inverters have a high surge power (e.g., 12400VA for the
6.2KW model) and a crest factor of 3:1, meaning they are
specifically designed to handle the high startup currents of motors
in pumps and air conditioners.
Q5: What is the warranty and how are service claims handled in
Thailand?
A: We offer a standard warranty with extensions available. Our
dedicated service center in Bangkok and partner network across the
country ensure prompt and professional support for any claims.
Q6: Does the high PV voltage (500V) requirement mean I need
special, expensive panels?
A: Not at all. Most modern standard solar panels have a Voc that fits
well within the 60-500VDC range. This high voltage limit actually
allows for longer series strings, reducing wiring costs and
improving efficiency.
2. Malaysia
Q1: With consistent sun year-round, will the inverter throttle my
solar input on very bright days?
A: No. The MPPT controller will operate at its maximum charge current
(e.g., 120A for the top model) but will not allow the PV input to
exceed the system's rated capacity, protecting your system while
harnessing the abundant energy.
Q2: Is the RS485 communication port compatible with my existing
BMS?
A: It is compatible with most standard BMS protocols for Lifepo4
batteries. We recommend consulting your battery's manufacturer or
our technical team to confirm specific compatibility before
purchase.
Q3: Can I set it up to only use the grid at night when tariffs are
lower?
A: Yes. Using the SUB output priority, you can set the system to use
Solar energy first, then Utility, and only use the Battery as a
backup. This allows you to charge your batteries with cheaper
off-peak grid power if desired.
Q4: The specifications show two different surge powers. What does
this mean?
A: The high surge power (e.g., 7000VA for the 3.5KW model) is for
starting heavy loads like air conditioner compressors. The
continuous power (3.5KW) is for running standard loads. This
ensures reliable operation for all your appliances.
Q5: How can I monitor my system's performance and savings?
A: With the optional WiFi module, you get real-time and historical
data on energy production, consumption, and grid usage, allowing
you to track your ROI and system health effortlessly.
Q6: Is professional installation mandatory?
A: For safety, performance, and to maintain warranty coverage, we
strongly recommend installation by a certified electrician or our
network of trained partners familiar with local electrical codes.
3. Nigeria
Q1: Can this inverter power a 1.5HP air conditioner during the
frequent power outages?
A: Yes. A 1.5HP AC has a starting surge of roughly 3000-4000VA. The
EM3500-24L model, with a 7000VA surge, can easily handle this,
along with other simultaneous loads like lights and a TV.
Q2: How does it protect my expensive appliances from damage from
generators or bad grid power?
A: The inverter acts as a perfect buffer. It conditions the power,
providing a stable, pure sine wave output (230V ±5%) regardless of
the unstable input from a generator or the grid, ensuring complete
protection for your devices.
Q3: My generator fuel is expensive. Can the inverter reduce my
generator runtime?
A: Absolutely. You can set the AC charger current to high (up to 80A)
to quickly charge your batteries with the generator, minimizing its
run time. Once charged, the inverter switches back to silent,
cost-free solar/battery power.
Q4: Is the "No Battery Mode" useful if my batteries are old and
failing?
A: Yes. This feature allows the system to operate directly from solar
panels during the day, even if your battery bank is disconnected or
no longer holding a charge, giving you immediate power while you
arrange for battery replacement.
Q5: What is the physical security of the unit? Can it be locked?
A: While the unit does not have a built-in lock, its design allows it
to be easily mounted in a lockable cabinet or a secure room, which
is a standard practice for protecting valuable equipment.
Q6: Are spare parts readily available locally?
A: We maintain a strategic inventory of critical spare parts like
fans and control boards with our authorized distributors in Lagos
and Abuja to ensure quick turnaround for any necessary repairs.
