It doesn't seem to. I am guessing the last image on the screen is a gauge and If I ran the batteries down that might change. We'll see. Does the voltage seem right given overcast and 94 degrees? Here's some pictures. A full shot of the front of the box and 2 pictures of screen while...

here are two pictures:

I have it all hooked up in parallel. I put a multi-meter on the 6 gauge wires in the combi box and read about 36v. Then looking at the readout on the inverter/controller it reads out at about 36v. It's fluctuating between 2-4a. Pete, the guy who designed it and drew me a diagram to hook it...

Just put the probes on the terminals or would that cause short/sparks?

It ran my drill. hoping to hook up panels to the combi box soon.

I ifinally attached the two batteries in series to the inverter/controller. I have no idea if this is how it should read or not. It doesnt tell me how charged the batteries are and I would think it should.

I am posting the input from some solar installers that are now helping me. I thought it might be of interest. It agrees with the advice given here. There help wasn't sought but offered when I asked for them to help me by selling me cables: See the wiring diagram below. This will be the...

That does look like it would be fun. Soon.

Here's an update. Couldn't get cords on labor day. Got a call back from the solar place on Tuesday and they want to review everything and help me rather than just make the cords for me. So, I have sent them all the specs and I am waiting to hear from them. They are not charging me anything...

There is no combiner since it was just 4 panels. All the y cables lead into a 16 foot, 12 awg extension cable. The panels are tight up against each other end to end in tilt braces facing south. The panels are about 18-22 feet from the box. they can come closer but then one panel will be in...

The sky was completely covered and obscured by smoke. A few cable connections were not tight. Hoping that's all it was, yes?

I agree, this is the first step. Right now what I need is to know: if 12awg cords and cables are sufficient to wire the 5 355W panels all in parallel. The label on the back of the panels say to use 12 awg and makes no mention of serial or parallel, so I assume they are right,but we talked...

Can I do that if I end up keeping the current combo unit which is not MMPT? Most recent comment on this post makes me wonder if I dont need to put the money inot more panels. He claims the size of the inverter compared to the much lower wattage of the panels will make the inverter winge and...

would these panels be a acceptable match to mine, if I cant get A-1 solar to sell me less than 4. https://www.ebay.com/itm/224569597351?hash=item3449641da7:g:jbwAAOSwg6hhEwEQ

I put the multi meter leads on the end of the positive and negative wire coming in off the solar array.

Thank you! So I cant do anything till I get fuses. When do you need a fuse when in serial-parallel?

After I originally hooked up the 4 panels in serial and parallel before hooking it up to the combo unit. I put a multi meter on it. It was completely overcast with smoke. The meter was fluctuating a lot but the high number I could catch repeatedly was 1740.

This seems like it could be a good match. same cell number and 350 watts is close to my 355. Both are mono. Perhaps they would sell me one for a good price. If the specs seem good and the listing says they are new. What do you think...

I can do that. On a completely overcast day my 4-355 watt panels produced around 1700-1760 watts when wired in serial-parallel. I've read say wiring in series can multiply watts. If so, what might these 4 panels produce if wired the same way on a Sunny day with the correct inverter and...

thanks! very nice.

Here are the batteries: https://www.eco-worthy.com/collecti...ies/products/100ah-12v-agm-deep-cycle-battery I have 5 panels total but said 4 cause I've been told you can't wire 5 in series parallel. I have 3 batteries and two matching on the way. They are all new. And I just posted a picture...

Oh I am confused alright! No doubt about it. This is over my head. Here are the batteries: https://www.eco-worthy.com/collections/components-batteries/products/100ah-12v-agm-deep-cycle-battery I have 5 panels total but said 4 cause I've been told you can't wire 5 in series parallel. I have...

I think I need to change that inverter/controller out in order to be able to be safe more days but I cant afford enough solar to prepare for the worst case. I can't hook all the panels up without more wires and "beefier" wires. I'm going to hook up just two to establish if it's in good repair...

yeah, okay. Can't do much more. I am trying to buy one more panel but that's not an easy thing to get anyone to do. I'm not savy electronically to figure out a used panel that is a match, so I wrote A-1 solar which is who sold me the 5 panels. they have a 4 panel minimum and a 195 dollar...

Thank You for shopping for me. Everyone is being so kind and helpful! I really appreciate it. I'd go larger to accommodate adding more panels. an example on Amazon: Is the example the larger or do I go up from there? If up from there, on which spec? When you say I can wire these all in...

Yes, I will try to just hook it up to two panels and batteries and if it all works then I can offer to buy an inverter in place of it. I did buy from Eco-worthy, not Amazon.

That is an option. But 4 hours wont be enough to keep us alive if we see days in a row of 115 degree+ days like we did in May, June and July. Under those conditions the cooler has to run 10 hours to keep us under 80. It's a risk to run this lean. 4 hours is the bare minimum under the best...

If we do not have overcast skies from all the smoke pouring in, then it will work. In serial, it would have worked even with the smoke blocking out the sky. That was the goal. I can put money into beefier cords and set upin parallel or I can just put the money into finding an...

Per hour. I agree. I need a new inverter and controller. We have a small generator but expect to find it difficult to get enough gas for it to be the solution daily.

I live in the second sunniest city in the country and the panels are set up with no shade at all. However, California has allowed fires to burn all summer, when simply calling out the national guard would have extinguished these huge fires. Enough is enough. I've been surrounded on 4 sides by...

12AWG 1 Pair Solar MC4 Y Parallel Branch Connectors MFF&FMM Pair 12AWG 16.4FT Solar Extension Cables Wires with Female and Male MC4 Connectors 6AWG 13 Inch Battery Interconnect Cable-two wires of 6 awg on each cable. If these all have to be replaced and I have barely enough power to run just...

Thank you so much for all your time and help. I can't hook the system up in parallel till I order more cords and until I know if it's at all feasible to run the cooler for 5 hours a day without harming this inverter, I dont know if I need more cords to wire in parallel to this combo unit or if...

So, wiring just 4 in parallel will not accomplish the perhaps life saving goal of running the swamp cooler for at least 4 hours which takes 1050 watts. I need to add the 5th panel, if that isnt going to dmage the combo unit. What do you think? I don't understand all the numbers. Sorry...
