To remedy this I’ll be using a DC to DC voltage converter to step up my 12VDC to 48VDC. Would it therefore not be better to have a very low-powered A/C unit that uses solar power exclusively, running throughout the hours of daylight, rather than a high-powered unit running for a few hours and requiring supplementary power from the grid? Cheers, Unable to add item to List. It is missing because there are extreme differences in our needs/uses. (Only about two weeks a year it’s that hot/humid in Ohio.). I just read your post. Inverter (2kw or 3kw). The portable AC unit I’m using has a SEER rating of 12, which means my new mini split system will be 225% more efficient once it’s installed. No, I just do a LOT of things to keep the house cool without running the AC. Too dam expensive! It lowers the amp draw from the batteries. At night I open the windows to allow the house to cool. One of these ideas is once I get a greenhouse built, have black plastic barrels filled with water that can circulate from the black roof hoses I’d use for heating bath water. Each 100 amp hour will draw down to 50% of battery discharge from full will give you 1 kw of usable power. DIY install. I too have learned this the hard way regarding if you don’t buy it from them they don’t want the jobs.

Without AC I can’t really sleep, even using a fan to passively cool the house. All the walls are well insulated, the windows are of very high quality, awnings and blinds (operated automatically by a home automation system) keep the sun and heat out as much as possible, and a heat recovery ventilation system (for summer, it should more accurately be called a heat removal ventilation system, since it cools in incoming air) avoids the need to open windows (and let in heat) to ventilate the house.

Granted, my conditions were a bit more extreme with regards to heat.. maybe a little less with regards to humidity.. (I’d have to check, but I’m pretty sure Charlotte, NC gets more humidity than Guaymas, Sonora). If you’re off the grid producing DC solar power, you’ll have lost 10% or more through your inverter to get AC power out, then lose another 10% or more changing that AC back to DC for the air conditioner compressor.

They are fast AND efficient to cool (or heat) the area of almost any decent size room that you are using. It also analyzes reviews to verify trustworthiness. They are made of narrow concrete blocks with concrete floors, concrete ceilings and single pane windows. A good voltage regulator that will cut power and switch to grid before your battery bank drops to low would be a good idea. Any update. I installed with a 48 volt battery bank and a six panel array to maximize run time (16 to 24 hours). To give you an idea: on a normal sunny day my solar panel power system makes about 8,000 Watts, but on a cloudy day (when the clouds are very thick with no gaps) I get between 2,000 and 4,000 Watts.
