Of course the grid-connected inverter can be applied tosuch as various types of photovoltaic modules, various types of batteries, DC switching power supplies, DC motors, etc. In the grid feed system or power supply type of load discharge, aging test and other systems. High Efficiency(Inverter build in MPPT):MPPT efficiency is above 99%. Advanced Maximum power point tracking (MPPT) to ensure the high efficiency of system. High-efficiency and frequency transformer, sufficient patents. Easy to Operate: This on grid inverter have LCD display, you can see the parameters on the display, clearly show AC DC input output parameters. There are four working model(normal PV mode, PV limiter mode, battery CP mode and battery limiter mode), you can set it by yourself. High Quality:This grid tie inverter made of aluminum shell which is hard, it is difficult to damaged. On grid inverter build in fans and aluminum shell which makes it fastly dissipating the heat.
