Inverter programming

The simplest off-grid inverters rely upon factory settings and do not permit any programming. The function of many standard off-grid inverters is to simply convert between DC and AC - there is not much adjustability that is required. As inverters become more complicated and begin to incorporate charging capability for use a generator and monitoring/communications platforms for improved system management the programming options quickly become complicated.

To program an inverter it is necessary to have manuals for the inverter any any other major components (communications/monitoring, generator) on hand.

Basic settings

• Low voltage disconnect: An inverter can be set to automatically cease inverter if the battery bank voltage reaches a certain minimum value in order to protect the it from deep discharges that can greatly reduce cycle life. Typically set at around 20% state of charge. It may be also possible to set the value at which the inverter begins inverting again to give the battery bank sufficient time to recharge - a higher value than 20% SOC is recommended.
