We do just fine running around 255AHs capacity battery bank. This is enough power to run our home entertainment items from an 120VAC source coming from an PSW INVERTER along with alot of other 12VDC items direct connected to the battery bank. We do just about everything we do at an electric camp ground except no air conditioner or high wattage microwave use.
We have beefed up our battery system to include additional batteries and smart mode charging technology. We have also replaced all of our incandescent automotive type bulbs for LED lights.
The idea here is to run all of the 120VAC items we want to run from an PSW Inverter and all of the 12VDC items direct connected to the batteries and then recharge the next batteries the next morning around 8AM with the 30AMP Trailer shore power cable connected directly to our 2KW Honda Generator 120VAC receptacle using an RV30A-15A long adapter.
We can re-charge our batteries back up to their 90% charge state in as little as three hours generator run time.
Now we are good to go for the next day/night battery run...
Does take some planning but works very successful for us now...
