Key Features
- 3kW rated AC and backup output, with 200% backup overload capability for 10 seconds.
- Two independent MPPTs, each rated at 16A, for flexible solar array layouts.
- Supports compatible low-voltage lithium-ion and lead-acid batteries.
- Generator connection, smart-load control and AC coupling for suitable system designs.
- IP66 enclosure, natural cooling and a 7-inch LCD with Bluetooth commissioning.
Where to Use
For single-phase homes requiring solar self-consumption, timed battery charging and essential-load backup. Off-grid and generator applications require a correctly designed system.
