This pure sine wave solar inverter has 97% efficiency and MC4 may meet your need.
Working principle:
Sunfine SMX series solar inverter off grid without charger and with MPPT controller.It can utilize the unstable DC input solar power, through DC-DC and DC-AC two procedures.To produce the high quality pure sine wave 220VAC electricity to the loads(water pump,motor,computer,led lights...).
Photovoltaic Grid-connected Power Generation System
Photovoltaic system converts solar energy into the electricity, then the grid- connected inverter change the DC into AC, and then send the electricity to the state grid.
It can work without storage battery. Lower cost, easy to install and operate, and length
lifetime of photovoltaic is the trend of solar energy development, representing the energy
utilization technology in the 21 century. Photovoltaic grid-connected systems have been used abroad in developed countries.
Just like the local utility grid, the inverter produces true sinewave AC electricity for your stand-alone or back-up power needs. Computers, TVs and pumps are just some of the examples of modern electronics
