Malaysia (Southeast Asia)
Q1: Does the EM series meet Malaysia's standards for residential solar systems?
A: While local certification may be required, the inverter's pure sine wave output and PF=1.0 align with international standards, ensuring safe and efficient operation in Malaysia.
Q2: How does it handle Malaysia's consistent solar exposure?
A: With a max PV input of 500Vdc and MPPT range of 60-500Vdc, the inverter optimizes energy harvest from Malaysia's abundant sunlight, increasing ROI for solar investments.
Q3: Is the Wi-Fi module easy to set up for urban homes?
A: Yes, the optional Wi-Fi module offers plug-and-play setup, allowing users in Kuala Lumpur or Penang to monitor energy usage remotely via smartphones.
Q4: Can it support small businesses with high power demands?
A: Absolutely! The 11KW model provides reliable power for shops or workshops, with overload protection (140% for 5s) ensuring safety during demand spikes.
Q5: How does the battery charging compare to traditional inverters?
A: The EM series offers up to 160A solar charge current, charging batteries faster than conventional models--perfect for Malaysia's energy storage needs.
Q6: What cooling mechanisms are in place for tropical heat?
A: Built-in thermal management and a wide operating temperature range ensure stable performance, even in Malaysia's hot climate.
Philippines (Southeast Asia)
Q1: Is the EM series durable enough for the Philippines' typhoon-prone areas?
A: Yes! The anti-shock terminals and robust housing withstand harsh weather. Its ability to operate without a battery adds resilience during disasters.
Q2: How does it address frequent brownouts in rural areas?
A: With a transfer time of 20ms for home appliances, the inverter provides seamless backup power, essential for Philippines' unstable grid.
Q3: Can it be used with portable generators?
A: While designed for solar and grid, the AC charger compatibility allows integration with generators, a common backup solution in the Philippines.
Q4: What solar panel configurations are recommended?
A: The dual MPPT supports two independent PV arrays up to 5500W each, ideal for maximizing limited roof space in Philippine homes.
Q5: Is technical support available locally?
A: Although specific support depends on distributors, the product's RS485 and dry contact interfaces facilitate local technician assistance.
Q6: How does the EQ function help in extending battery life?
A: It prevents battery stratification and corrosion, crucial in the Philippines where high temperatures accelerate battery degradation.
Nigeria (Africa)
Q1: Can the EM series handle Nigeria's unstable grid and voltage spikes?
A: Definitely! The wide input voltage range (90-280VAC) and overload protection safeguard against grid irregularities, common in Nigeria.
Q2: How efficient is it for off-grid homes in rural Nigeria?
A: With 94% peak efficiency and the ability to work without a battery, it reduces energy waste and costs, perfect for remote communities.
Q3: Is it compatible with deep-cycle batteries used in Nigeria?
A: Yes, the CC/CV charging method supports deep-cycle lead-acid batteries, while RS485 enables future upgrades to lithium batteries.
Q4: What is the maximum discharge current for high-power appliances?
A: The EM11000-48L offers 220A discharge current, capable of running refrigerators, water pumps, and lighting systems simultaneously.
Q5: How does the MPPT perform in Nigeria's sunny climate?
A: The MPPT technology ensures maximum solar energy harvest, leveraging Nigeria's high solar irradiance to cut diesel generator reliance.
Q6: Are there options for system expansion?
A: While parallel capability is not supported, the high capacity and modular design allow for scalable setups in Nigerian homes and businesses.
