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
