DC 12v 7,000BTU Air Conditioner on a 2020 FourWinns v255OB by Mabru Power Systems

This is an overview of an installation done by us on a customer's vessel who needed air conditioning but did not want the hassle of a generator on his vessel.
The AC heats and cools, will run for 8 hrs on the single battery installed by us and we added an inverter to allow the use of 115v appliances while disconnected from shore power.

*This unit works like a charm. Keeps my rv 21 x 41 very **Fastly.Cool** . I recommend to anyone that wants to keep a rv cold without having to turn on the main a/c.*

How much $ including installation?

How many square feet is the 7000 but good for?

[@USA-GreedyMenOfNoIntegrity]

150 sq ft if well insulated.

How long can this setup run the AC on the house bank?

[@MabruPowerSystemsINC]

runtime on our 250ah Lithium is 8hrs with the unit of full speed. this runtime would be affected by how many other consumer are running such as refrigerator, stereo and inverter.

@@MabruPowerSystemsINC Thanks. Have you tried any "real world" tests that take into account the unit running at lower speeds once desired temp is achieved, other likely uses, etc.?

Is the air conditioner an AC or DC unit?

[@MabruPowerSystemsINC]

The unit is 12v, it is not working through an inverter.
