This document describes a multi-function inverter, combining the functions of an inverter, solar charger, and battery charger to provide uninterruptible power support. It features a comprehensive LCD display for user-configurable and easy-accessible button operations, allowing adjustments for battery charging current, AC or solar charging priority, and acceptable input voltage based on different applications.

Function Description

The inverter is designed to provide power for various appliances in home or office environments, including motor-type appliances like tube lights, fans, refrigerators, and air conditioners. It can operate with utility mains, a generator, or PV modules as input sources.

Basic System Architecture: The inverter integrates into a hybrid power system, utilizing solar power, a generator (or utility), and external battery packs to supply power to home appliances.

Operating Modes:

Standby Mode: The inverter is not turned on for AC output, but it can still charge batteries from PV energy or utility.
Fault Mode: Indicates internal circuit errors or external issues such as over-temperature or output short circuits. In this mode, PV energy and utility can still charge batteries.
Line Mode: The unit provides output power from the mains and charges the battery. If "solar first" is selected as the output source priority and solar energy is insufficient, both solar energy and utility will supply the loads and charge the battery.
Battery Mode: The unit provides output power from the battery and/or PV power. If "solar first" is selected and the battery is not connected, solar energy and utility will provide the loads.

When to Equalize: Initiates in the floating charge stage when the equalization interval is reached or activated immediately.
Charging and Timeout: The controller charges the battery until it reaches the equalization voltage, then maintains this voltage until the equalization timer runs out. If the battery voltage doesn't recover to the equalization point, the charge controller extends the time.

Maintenance Features
