Off-Grid Solar Inverter
Features of the Off-grid Solar Inverter
1. Multi-setting
The off-grid solar inverter can operate in either PV priority mode or AC priority mode.
Users can choose the charging current based on the configured capacity of the battery.
2. High reliability: Double CPU digital control
Independent MPPT (Maximum Power Point Tracking) control microprocessor system and independent inverter microprocessor control system are available.
3. Isolated and pure sine wave technique
4. LCD+LED display mode
5. The off-grid solar inverter comes with wide iSPut voltage range.
6. High-speed synchronous conversion
The solar inverter system can track the mains power's phase automatically, and make sure the inverter's output voltage is the completely same as the mains supply's voltage.
7. User-friendly alarm system
Unattended and intelligent monitoring system is available. The off-grid solar inverter can communicate with the PC by RS232 or USB interface. It can also realize remote monitoring, testing and regular shutdown/ starting-up operation by SNMP network system.
8. Online protection function
Intelligent no-load auto shutdown technology is optional.
Applications
PI series off-grid solar power inverter uses digital intelligent control, and complete high frequency conversion topology, with high reliability and strong anti-interference. The rating iSPut voltage is 24V/48V and rated power rating is 1KVA, 2KVA, 3KVA. It is used in the solar power supply systems of communications, transportation, islands, borders, rural, pastoral areas, etc.
