Tigo GO Battery Module Delivers Expandable 5kWh Storage
The Tigo GO Battery TGB-5 Module Kit adds 5kWh of lithium iron phosphate (LFP) storage to a Tigo GO Battery system. Each module has its own DC-DC converter that boosts battery voltage to 380V, and up to six modules connect in parallel to one TGM-30 BMS for 5 to 30kWh.
The GO Battery works with the Tigo EI Inverter. Solar powers your loads first and any excess is stored for later.
