 For Off-grid systems, its strongly recommend to make sure there is a minimum of DC-Coupled PV (= MPPT Solar Charger) in the system. Ie. not only AC-Coupled PV. Also, minimum battery configuration, and factor 1.0 are always important to adhere to, and even more so in case of Off-grid systems. Both BYD and Victron will be reluctant or even refusing to give support to systems that are not sized according to the minimum battery configuration table.

 In a correctly configured system, the inverter will shut itself down before the batteries enter a self protective shut down state.
-If your system is charged only with an AC-coupled PV inverter, this may prevent the AC-coupled PV inverter from starting up to recharge the batteries. Therefore it is strongly recommended that there is also either a generator or DC MPPT charge controller to provide DC bus power to bring the inverter back online to allow normal recharging to resume.
+Therefore it is essential that there is also either a generator or DC MPPT charge controller for overall system stability. If your system is charged only with an AC-coupled PV inverter, this may prevent the AC-coupled PV inverter from starting up to recharge the batteries.
 Even a single 100/20 48V MPPT charger unit with 2 x 60 cell solar panels would be sufficient to add this self correcting mechanism able to maintain the DC bus voltage and improve longterm system reliability considerably from accidental deep discharge and subsequent shut down.
