Although solar pump inverter built in high efficiency MPPT tracking arithmetic, up to 99.6% MPPT efficiency, but also need to consider many factors of solar radiation. It is no certain rules to determine exactly how many piece solar panels exactly input for system. If the output frequency can’t get to 50Hz/60Hz, please consider to connect more solar panels




Q1:What is the payment terms?
100% T/T in advance for sample order. 50% T/T in advance, banlance 50% T/T before delivery for bulk order.

Q2 : What's the different between inverter and solar inverter?
Inverter is only accept AC input, but solar inverter not only accept AC input but also can connect with solar panel to accpet DC input, it more save power.
