Fogstar Battery Integration
The GEN3-LB-EU is designed around 48V low-voltage battery storage and provides seamless integration with compatible Fogstar Energy batteries.
High-current battery support enables rapid charging from surplus solar generation, off-peak grid electricity or a connected generator.
Battery specifications:
- Nominal battery voltage: 48V
- Battery operating range: 40-60V
- Maximum charge/discharge current: 80-125A, model dependent
- Maximum charge/discharge power: 3.6-6kW, model dependent
- Battery force wake-up from PV, grid or generator
Solar PV Input
Dual independent MPPTs provide flexible solar array design and allow separate PV strings to operate independently, making the GEN3 particularly suitable for east/west roofs, different roof pitches and multiple solar orientations.
- Maximum PV input: 6,600-12,000W, model dependent
- Rated PV input voltage: 360V
- Maximum PV input voltage: 530V
- MPPT operating range: 60-425V
- Start-up voltage: 50V
- Number of MPPTs: 2
- MPPT configuration: 1 / 1
- Maximum PV input current: 20A per MPPT
- Maximum PV short-circuit current: 32A per MPPT
- MPPT efficiency: 99.9%
Generator Integration
Integrated generator support allows the GEN3 to manage power from solar PV, battery storage, the electricity grid and a generator within one energy-management system.
With generator input of up to 12kW, it provides additional flexibility for properties requiring greater energy independence or backup capability.
Fast Backup Power
The GEN3 provides rapid 7ms backup switching during a grid outage.
Its double-rated surge capability for up to one second also provides additional support for appliances and electrical equipment with higher start-up power requirements.
Expandable up to 16 Inverters
For larger installations, up to 16 GEN3 inverters can operate in parallel.
This provides a scalable platform for systems requiring greater inverter capacity and allows energy-storage installations to be expanded as requirements increase.
