Time-Based Energy Management

The FSolar JUP G1 allows battery charging and discharging schedules to be configured according to the required operating times.

This functionality can help users:

• Charge batteries during selected periods
• Use stored energy during peak tariff hours
• Reserve battery capacity for emergencies
• Maximise the use of daytime solar production
• Control generator-assisted battery charging

On-Grid, Off-Grid and EPS Operation

The inverter supports flexible operating modes for different power requirements.

The EPS output can supply selected essential loads during a utility power interruption.

Independent Generator Input

The inverter includes a dedicated AC input port for a compatible diesel generator. Generator power can be used to operate connected loads and store energy in the battery system.

This feature is particularly useful for remote locations, farms, workshops, and areas with an unstable electricity supply.

Parallel System Expansion

Up to 20 compatible inverter units can be connected in parallel for off-grid operation, allowing the system to be expanded for larger power requirements.

Parallel installations must use compatible inverter models and follow the approved wiring, communication, and programming procedures.
