What do I do if there is an Error 53 on the display?
What do I do if the baery icons on the display don’t match
the number of baeries I have?
What do I do if there is an Error 19 on the display?

• Put the BMS in detecon mode.
• Conrm all modules are ON with a green light around
the ON/OFF switch.
• Wait unl the modules count matches the screen.
• Conrm the address of the modules are set according to
the Install Manual page 11.
• This a parallel detecon mode fault. If the system is in
parallel, please check the communicaon cable between
the master baery system and the connected baery
systems in parallel.
• Set inverter DIP switches to parallel detecon mode to
rediscover the paralleled baery system.
• Set the parallel stack to the appropriate address (see pg
12 of the Install Manual).
What do I do if there is an Error 20 on the display?

and charging to 100% SOC.
• There is cell damage on one of the cell packs. Call Tech
Support for assistance.
