JAJE 20KW grid connected inverter
1. DC side ZVS BOOST circuit has lower power consumption and more reliable circuit.
2. network side is a multistage switch H-Brigde circuit, and the common mode voltage is very low, which is more suitable for the domestic rural power grid.
3. the highest efficiency of 98.7%, wide range input voltage;
4. built-in DC switch, easy to install and debug.
5. no transformer, no fan design, longer life;
6. multi-channel high efficiency MPPT technology, can be individually input, and can also directly cross link input;
7. big screen LCD monitoring, no need to set up;
8. IP65 design, outdoor installation;
