I've assembled a few systems but this is the first system I've specced. It's designed for a small van (Renault Trafic) with a fairly small demand - USB chargers, fridge, heater.
Orion-tr 30A, SmartSolar 75/15, BlueSmart 12/17, BatteryProtect 12/24-65A, BMV-700, 100Ah AGM battery.
I'm not sure whether I need a BMS or not.
