FAQs from Different Countries
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.
