Re: Why No Inverters for Deep Cycle Batteries?

No such thing as a 12 Volt deep cycle battery that can be drawn down below 10.5 Volts *and then be fully recharged.*

In fact, the "RV" type aren't even true deep cycles and won't take even normal off-grid use for very long.

If you do draw a battery down below its "dead" point you can run in to the very interesting (and unrecoverable) state of reversed polarity.

The current increase would be mind-boggling. 1200 Watts @ 12 Volts is 100 Amps. @ 5 Volts it would be 240 Amps.

1220 Watts of PV, OB MX60, 232 Amp hrs, OB 3524, Honda eu2000.

Ohm's Law: Amps = Volts / Ohms

Power Formula: Watts = Volts * Amps
