We have a Multiplus 3000 with a 12V 300AH Lithium battery bank (Battle Born brand). Also has 350W solar panels and a Smart 100/30 Charge controller. Recently ran the batteries low enough that the Multiplus shut off. Continued to pull house 12VDC current to run the furnace etc., which eventually pulled the batteries low enough that they shut themselves off (built in BMS). The next morning, fired up the generator, but the Multiplus would not come on. Later, when the sun came up, the batteries charged enough that they turned back on. Wala! The Multiplus came on.
Is there a setting whereby I can force the Multiplus to come on even if it detects no batteries?
