Do you have a voltmeter to check the battery voltage against the monitor? Did the monitor manual have anything about calibration? And you can also check the connection between the battery and inverter. What gauge wire between the battery and inverter? I have a Renogy 700 watt inverter, but...

If you ran for about 3 days at 1200 watts per day that would run your battery down below minimum voltage. Check your battery voltage. The good news is you ran about 3 days with no sun. If you are not using a shunt-based battery monitor, you'll have to be more careful with watts in and watts...

I use 3/4 inch EMT with flexible panels for a portable system. Even with light weight flexible panels, it needs lots of bracing.

My system was installed in 2017 and I haven't looked at the tax description since. Requirements may have changed especially since California's had so many grid issues. Something like a backup power system.

I have a portable system for my daughter's house. Had it up and running by 11AM the morning after hurricane Ida. It uses 12 175 watt (2100 watts) Renogy flex panels, 3k Growatt inverter and 15k battery bank. Worked fine, but I'll say you can never have too much solar. The panels are easy to...

Pretty much every inverter will have a fan. Smaller Victron charge controllers have a heat sink, so no fan. I have two Midnite CCs and a Cotek inverter. They are in an enclosed patio and the fans for the inverter never stop. The CC fans are on from sunup to sundown.

I have 4 small inverters and MPPTs wrapped in foil inside a sealed metal box and recycled amorphous solar panels as backup. Besides that, I have lots of components that I've outgrown as I've upgraded. But for an EMP even, my focus is on food, water, hygiene, first aid and defense. I live on...

I think it's 1/12.

This started out as a backup system for power outages and hurricane season. It was a 24v 2000 watt kit from Renogy with 8 panels. My wife said no holes in the roof, so Ecofoot was perfect. It went together and was producing power in 2 days. It went so well; I bought 12 more panels and made...

Silicon seal. Things have changed so much since that install. Those are 255 watt panels.

I need them for wind deflection during hurricane/storms. But no, they aren't needed. One caveat, if you don't use them, you need to ground them. The wind shield connects the panels and you only have to ground at the end of each row. I think there's a white version of the base. Let me look...

This is the first 2 rows. There are 5 rows of 4 panels now. The difference is the first row has 3 cement blocks the sides have 2 blocks. There is a pitched roof to the right (behind the array) and to the left with provide additional wind protection.

Will do. If I can't find any, I'll take some pictures tomorrow.

If the batteries are full, there won't be any demand and the panels won't push any power. You need more demand for the panels to produce more power. If you change the inverter setting to run from battery only for a few days and deplete the battery to 50%, than change it back to solar, you can...

It's not paranoid to understand that your plan and goals may be meaningless to a powerful organization that has its own plans and goals.

Be prepared for government agencies and military to confiscate anything and everything. When they roll in, it won't be to help. Guns and fuel first, then forced evacuation even if your area is not damaged and people have nowhere to go. Read about hurricane Katrina and use it as an operational...

Thanks Hedges. Bad eyesight here. Thought I saw DC voltage.

Looke like a wood beam between the metal roof and unistrut so you are making the ground connection between the roof and the panel rack. Could be a pinched cable somewhere. Make sure cables are clipped to panels or in conduit and ground only the panels and frame to a separate ground rod close...

The flat washer with the wingnut may be preventing a flat secure connection. Try replacing both with a regular bolt and tighten to spec.

Dirty power yes, but I'm in Louisiana, so it's not too much different from my grid power. I also have the 40v 300 watt inverter.

Here's an off the shelf setup. I use it for camping and the usual power outages at home. Some items will probably be on sale for Christmas. https://www.homedepot.com/p/RYOBI-ONE-18V-Cordless-Compact-Area-Light-Tool-Only-P796B/317327006...

You could add a separate charge controller for some or all of the load if you want to stick with the fanless inverter.

offgriddave, Here's the parts list and pictures. These are easy to move around and stack. The zip ties leave a nice gap to improve ventilation. But I've never put much stress on the batteries to heat them up. I used hot glue to attach the bus bars to the plastic case of the middle battery...

I've only used it a few times. Hurricane Ida and a couple of storms that caused power outages. I have 12 175watt Renogy flex panels along with a 3000 watt Growatt. This is a portable system for my daughter's house. I had everything up and running the morning after Ida. It ran fine, but...

Battery Hookup has some 10AH packs ebike packs. Not Lifepo4, but the price may be right. BH also has 75AH Lifepo4 cells if you want to build a battery. The ebike batteries are usually somewhat weather resistant if you keep the original case...

I'll risk it! https://www.silent-yachts.com/silent80/

IronRidge makes everything you need, but you have to order things separately. The sales rep can give you recommendations based on roof and shingle type.

Shading could be an issue. if so, panels with optimizers, second hand amorphous flexible panels or second hand Solyndra Solar panels could be used.

If you are running just a deep freeze, you should consider getting a stand-alone inverter for just for the freezer. You are losing about 1.5k just running the inverter. I'm not sure (check the manual), but you may be able to turn off the Growatt inverter while continuing to charge your...

Keep us posted on battery performance. Thanks!

I use it for a 20-panel roof array. Since 2017, it's been through a couple of hurricanes (100+ MPH wind speed) and several storms in south Louisiana.

Can you use a ground mount or mount on a shed? I didn't think 12v/24v needed RSD.

Yes, add new strings with separate charge controllers. Connect them to a common busbar connected to your battery bank. Add a DC breaker to control each CC. Be careful not to exceed max charging amps for your battery bank.

Northern Arizona Wind and Solar has all shapes and sizes. I've purchases lots from them, but no solar panels (yet). https://www.solar-electric.com/ https://www.solar-electric.com/residential/solar-panels.html?p=3&product_list_order=watts
