pv system tied with grid and battery bank work on both pv system and grid

Tanfon factory supply: off grid solar system, on grid solar system, on and off grid hybrid solar system, off grid solar system without battery.

We provide complete set solar power system that include all parts for customers, installation tool can be choose. Customers can easy install the system according to our detailed connect diagram and user’s manual.

On and off grid solar system working way:

1. Inverter transfer solar panel DC current to AC current, supply solar power to run loads directly, if solar power is excess, the power will charge to battery automatically. When the battery power is full also, inverter will send the excess power to grid. grid power to the load(by pass).
2. When the grid shut down, it will switch to off grid status, transfer solar DC power to AC power,supply solar power directly to the load.When the solar panel can not provide enough power to the load, it will use battery power.
3. When the solar panel only generate few power, it will switch to grid, supply.

Solar+Grid mode

1- when plenty of solar, solar provide power to load and charge battery, excess solar is fed in to the grid.

2- when solar is not enough, solar and city power provide power to load and charge battery.

3- When AC fails, solar and battery provide power to load.

4- when no solar, city power provide power, if city power fails, battery provide power.
