Introduction
This off-grid PV inverter can provide power to connected loads by utilizing PV power, AC power
and battery power. When PV energy is sufficient, it will power connected loads and charge
battery. When PV energy is not sufficient, this inverter will power connected loads and charge
battery from AC power source. When both PV energy and AC power source are not available,
it will provide battery power to connected loads.
Figure 1 Basic Off-Grid PV System Overview
Depending on different power situations, this hybrid inverter is designed to generate
continuous power from PV solar modules (solar panels), battery, and the utility. When MPP
input voltage of PV modules is within 150 VDC to 500 VDC, this inverter is able to generate
power
to the load
and charge battery. This inverter is only compatible with PV module types of
single crystalline and poly crystalline. Do not connect any PV array types other than these two
types of PV modules to the inverter. See Figure 1 for a simple diagram of a typical solar system
with this hybrid inverter.
Note
: When PV input voltage is lower than 250V, the power of inverter will de-rate.
