The installation of our two Sunny Islands is nearly complete.
I have question about the AC2 terminals and using a generator. Our two Sunny Islands (Master+Slave) are configured for 120/240v split-phase operation (2phase2) on the AC1 terminals. They are completely off-grid. In the event our solar system (Sunny Boy connected to AC1) cannot keep the batteries charged (dark days no sun), must we use a 120/240 volt split-phase generator on the AC2 terminals? Or can we use a (1-phase) 120 volt generator and parallel the AC2 terminals so the generator is feeding both AC2 terminals on the Master and Slave.
If not, is there a work around? Could a 1-phase 120 volt generator be hooked to just the Master alone?
Thanks!
