Built in a rugged, insulated NEMA 3X enclosure and skid-mounted for easy siting, the MOBICELL-350 integrates solar panels mounted on the outside walls of the cabinet, a 20 kWh AGM battery bank, and a 350W Solid Oxide Fuel Cell (SOFC) powered by propane. This Quality Assurance Framework for Component-Based Solar Home Systems was adapted from guidance documents originally developed by Global Sustainable Energy Solutions Pty Ltd (GSES) for the Government of Uganda. These documents were edited by staff at the Schatz Energy Research Center and Kevin. The MOBICELL-350 is the cabinet-mounted counterpart to our proven MOBISUN-350 trailer system. The most powerful unit ever built with single-phase inverter that can be configured in a 1-phase or 3-phase power system.

This is a technical guide for those with a basic understanding of solar and off-grid inverters. Solar and battery storage systems should always be installed by a licensed electrical.
