Product Overview
The cabinet integrates all critical off-grid power components into a single professionally assembled enclosure, reducing on-site installation time and eliminating the complexity of building a system from individual components. The four independent MPPT controllers allow multiple solar array strings to be managed separately, improving yield and providing redundancy.
The Victron SmartShunt 1000A provides accurate battery state of charge monitoring via Bluetooth, accessible from any Android device without additional hardware. The Solar Assistant controller monitors inverter performance in real time and provides remote access via Wi-Fi at no ongoing cost.
