On-Grid Inverter with Energy Storage System

These inverters can be connected to Melasta Energy Storage Systems and provide the power during the power blackout and save money. These are the features

1. Self-consumption and feed-in to the grid
2. Programmable supply priority for PV, Battery or Grid
3. User-adjustable battery charging current suits different types of batteries
4. Programmable multiple operations modes: Grid tie, Off grid, and grid-tie with backup
5. Built-in Timer for various mode of on/off operation
6. Multiple communication for USB, RS-232, Modbus and SNMP
7. Monitoring software for real time status display and control
8. Custom-made firmware by ODM contract
9. Parallel operation up to 6 units for 5KW / 10KW and 15KW

This off-grid inverter is a flexible and intelligent hybrid inverter that uses solar energy, AC utility, and battery source of power to provide continuous power. It‘s a basic and smart solar power storage system for house users to either store power into a battery for night-time use or usage for self-consumption first depending upon needs. The top priority for power sources is programmable with smart software. Throughout evening time or power failure, it will automatically eat scheduled power from the battery This way, it will lower dependency on the utility.


1. Money Saver
This Off-grid inverter can save money by utilizing a battery. Energy initially when PV energy is reduced. Up until the battery, energy is reduced, inverter will take in AC power from the grid.

2. Power backup when AC Fail
This Off-grid inverter can operate as an off-grid inverter to supply continuous power also without the grid. It‘s an excellent power service for remote regions or a temporary A/C source of power for outdoor camping or night market.
