Rikadoo Posted December 20, 2022 Share Posted December 20, 2022 For the last couple weeks i have sleeping out in my coach ,The 1st week i took myself out to a local camp site and was plugged into a 30 amp box. Because of the cold weather i found to save the propane heater from running so much, i use a electric heater, which keeps the whole rig comfie an warm with a temperature of 68 to 70 degrees, its quiet and according to the EMS read out and my surge protector it uses 13 amps. So now the project is compleated, i go to a different location and there im pluged into a 15 amp service. I found that the electric heater still worked fine, last night as i went into the rv to go to bed i discovered i had left the electric heater on. That is not normally my plan due to safety as well as costly, so be it note to self to be more aware, so as im getting ready for bed i hear my propane heater cycle on as its done before, however it sounds “different” like the motor is slow. I open my cabnit to view the EMS and the battery voltage i see the battery statis at 11.5 volts??? Thinking the worst that i may have a issue with my inverter / charger i look at the amperage usage and its showing 14 amps, i figure im close to my limits so i figured turn off the electric heater an see what happens. Now the EMS read out changes from 14 to 7 amps and almost instantly my battery voltage starts climbing, at that moment i realised a couple things, one is dont leave the electric heater on when not there to watch it, (Duh) the other is when the inverter / charger is battling for line voltage it deferes to taking a smaller amount rather than overloading the incoming circuit total, something i had no idea it was capable of doing. So having left the electric heater off all night now the EMS readout is at 5 amps which is still 3 amps higher than where it normally runs, battery voltage is at 13.8 and as soon as the batteries finish there soak charge im hoping to see the Ampreage return to its normal 2 to 3 amp draw, i kinda figure that lesson was a early Christmas present.
