Figure 1 Basic hybrid 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
acceptable range (see specification for the details), this inverter is able to generate power to feed the grid
(utility) and charge battery. Never connect the positive and negative terminals of the solar panel tothe ground. See Figure 1 for a simple diagram of a typical solar system with this hybrid inverter.
Note：This inverter is only compatible with below grid input. The voltage between phase 1 and phase 2 is equal
to phase 1 to N plus phase 2 to N. It doesn’t support single-phase or three-phase input.
The phase angle between L1 and L2 is 180°.
