Helios III(H3) series cost-effective off grid inverter, including 24Vdc/3.5Kw and 48Vdc/5.5Kw. Supports battery-free operation. Built-in MPPT solar charge controller supports solar panel input 120Vdc-450Vdc, open circuit voltage 500Vdc, maximum solar panel input power up to 5500watt, charging current up to 100Amp, remaining part can be directly supplied to the load. The AC charging part adopts the latest bi-directional charging technology, and shares the transformer with the main inverter, so that the period charging current up to 80Amp. 24Vdc/3.5Kw supports up to 2000Watt AC charging, 48Vdc/5.5Kw supports up to 4000watt AC charging. 3.5Kw/5.5Kw pure sine wave AC output, suitable for all types of loads, such as: refrigerators, air conditioners, compressors, motors, etc. Double peak power makes it support more ability to carry load. It is the best choice for solar system in home/RV/yacht/office, etc.
Battery-free operation function makes solar system less costly to build. Use solar panel to supply power directly to the load in good light conditions to complement utility power. Use RS232/RS485 to manage with BMS of lithium battery through Modbus or CAN communication protocol to make the system run more stable and to protect the lithium battery safely to make its life longer. Support WIFI or 4G to realize cell phone APP to monitor the system.Helios III(H3) series off-grid inverter makes you set up off-grid solar system with lower cost, powerful and stable. It is your best off-grid inverter choice.
