Inverter
The maximum continuous DC current must be considered carefully when pairing a battery bank with an inverter. The
inverter cannot have a higher maximum DC input than the battery bank’s maximum DC output. Otherwise, the BMS in the
battery may shut off due to discharge overcurrent protection. An oversized inverter may irreversibly damage the battery
bank in a worst-case scenario. The example below shows minimum battery bank capacities for various sizes of 12 Vdc
inverters with estimated discharge times at full load.

Properly size the battery bank’s capacity to the inverter to prevent battery damage.
Match the battery bank’s maximum pulse and continuous discharge current to the inverter’s maximum surge and input
current, respectively.
Use only inverters that have been certified to conform to UL 458.
