Solar Off grid inverter

1. Toroidal transformer of light weight, small size, high conversion efficiency, low power consumption, good load capacity and load adaptability, etc.

2. AC input automatic voltage regulator (AVR), input voltage range of 145V ~ 275V.

3. Liquid crystal (LCD) display, backlight power saving mode. The main display real-time battery voltage, battery capacity, input and output voltage, output frequency, duty ratio, etc. Automatically switch the display according to different working conditions.

4. Having overload, battery overcharge, over discharge, output short circuit, over-temperature protection features.

5. Full SMD modular structure, stable performance, easy maintenance.

Off grid solar charge controller
Solar panels may make power at very high voltage and current. If all that is fed directly to the battery then it may get overcharged or blast (in extreme cases).

A solar charge controller prevents this from happening. It is is placed in between the solar panels and the battery bank to regulate the charging (current and voltage) of the batteries through solar.

Basically, without a charge controller it is not possible to safely use solar energy for charging batteries.
