First time putting together off grid system

[swiftbug2]

First time Ive planned and put together a system.
This is a picture of the diagram I came up with. Each fuse is a manual reset. Ended up getting breakers for the switches. Probably could a got away with just the regular breakers for the fuse and switch instead of 2 separate things. Just wanting someone to look it over and let me know if I need to change anything before I go at it. Built the system primarily for my freezer in case of any extended grid down issues. Freezer is a 115v 1.1 amp I plan on keeping full even if with just bags of ice. Got a top mount fridge at 115v 6.5a estimated at 411kwh/yr and I'm wondering how long these batteries would keep it running. I found figuring out fridges for these systems to be the most confusing.


Currently have 4 panels

8 12v 100ah batteries

Whether this will work as is or not, you’ll need some data on how much energy this fridge And freezer consumes. Recommend plugging a killawatt meter into it and collect data to see over a number of days how much.

Between the fridge and the freezer, you appear to have 700 - 800 watts of load. I suspect you will pull more than you are making from your panels unless the fridge cycles on and Off only a couple hours a day. I don’t collect data except for my absorption fridge and it is on about 12 hours a day, give or take a couple of hours.

The Batteries have a total of 9.6 kWh, but on a day to day basis, you would want to limit this to 4.5 kWh To keep from killing the batteries and having a reserve for the next day.

For how much energy your panels bring in, need to do an off grid calculator or as in my signature block or PV Watts. I suspect your panels will produce between 2 kWh and 5 kWh a day.

Looking good, aside of course from what Chris has said, the only thing I'd pick out is the wiring of the battery bank

The way you've layed them out would result in unbalanced load sharing and in the end reduced the life of the bank

This would share the load more evenly



Or try method 3 from the smart guage guide

SmartGauge Electronics - Interconnecting multiple batteries to form one larger bank

Hello Im looking at puting solar panels on my garage to power my garage consumer unit here is my original design. should I add a DC isolator between panels and inverter? and should I add an AC isolator between the inverter and garage CU?
Also taking a 40amp breaker off the main CU to power the garage when the solar is not working is this ok.

Any feedback would be good
