“Although be aware that this value is deceiving due to other efficiency losses (heating/wiring resistance/Inverter switching). The maximum safe “continuous” amps to draw from a battery is AH/10. So if your battery has a 100Ah rating the maximum that should be drawn is 100Ah/10=10amps max over an extended period of time. If you’re just running a power drill or high current appliance for a couple minutes then it shouldn’t bother it. Voltage ratings The common voltage ratings for a solar setup are 12v, 24v, 48v.”

“Batteries are rated by an Ah (Amp Hour Rating).  The rating is given by the manufacturer as indicator to how much current the battery can supply over a given amount of time. 10Ah = 10amp load for 1 hour or 1 amp load for 10 hours.
