I started out with a hundred watt solar panel and a charge controller and changed my battery to lithium but now, I'm doing 400 more watts on the roof and a bigger inverter and a shunt and another battery and a few other things I can't think of right now. I'm just wondering how you guys fit it...

So, I have some 540w solar panels, a 1500 w inverter and a 100 amp 12 volt lithium battery with a .5C charge rating. I want to run my swamp cooler from it this summer and it takes about 400 w. What I'm wondering is, what should the specs of the mppt charge controller be and will one of these...

Hello again, I have one of these inverters (bottom of page) and I cannot find any info on how it wires into the breaker box on my camper. All the manual says is, connect AC out but it gives no reference as to where in the breaker panel it connects. Will Prowse has a video on YouTube that...

Wondering if there are inverters that can do 240 split phase without being 2 in parallel. All I see are inverters that must be wired 2 in parallel to feed both lines of your house. Is there an inverter that can do split phase 240 without the need to be paralleled with another inverter?

So, I just got to new 12 volt 100 amp hour batteries and I know that when you connect them in parallel, you should have the negative of your inverter going to the negative of One battery and the positive of your inverter going to the positive of the other battery to better balance things out...

Just giving this battery its first charge and I wind up with a cell that is going haywire! What do I do now?

I was looking at the eg4 6000xp and now I see that it has a list of compatible batteries. Does that mean that any old 48 volt battery will not do or just that it won't communicate with the inverter? does a person really need communication from the battery to the inverter?

This looks like a PowerMax converter but it's rebranded and being sold on Amazon. I was thinking about installing it in my camper for my 12 volt 100 amp hour PUPVWMHB lifepo4 battery. PM3-55 RV Power Converter | Replacement for Pm3-55 WFCO WF9855 | 55 Amp | 110V AC to 12V | Compatible with...

I have a nice older double wide mobile home with a metal sheet roof that I want to install a few solar panels on. I would rather not drill through the roof but, I'm open to any suggestions. You guys got any ideas that would last a long time? Thanks.

I currently have this battery:https://a.co/d/aa6Ygy8 And, I'm thinking about adding another one to it in parallel. Does it matter if I get one exactly like it that has Bluetooth or if I take the Lesser priced one from the exact same manufacturer that does not have Bluetooth? I mean, what would...

I'm sure I'll get some Flack for this out of the rich guys but, here goes. I had my mind all made up to go ahead and blow the money on an eg4 6000 XP but after I started adding up my loads, I think I'm going to need at least 10 or 12 KW. The 12,000 XP is $2,500 before tax! That is just more...

These panels are almost 4 ft wide but they give you pretty short cables coming off of them because they're meant to be put in series. I have to put two of them in parallel to accommodate my solar charger so, I was wondering if you guys have some cool, smarter way of doing it. I need the cables...

This is with no loads at all. The inverter is turned off. When the mppt says it's putting out 650 watts, the BMS app only shows about 350 coming in.

How many of these panels can I put on this inverter? Inverter specs: SOLAR INPUT No.Of MPPT 2 Max.PV Array Power 5,500W+5,500W Max.Input Current 22A+22A Max.Open Circuit Voltage 500Vdc+500Vdc MPPT Voltage Range 125~425Vdc

I'm doing lots of upgrades to my old '91 truck camper. It's still in nice shape so, there's no reason not to. Anyway, I have installed a lithium battery and solar and I decided that I would like to upgrade my converter. I bought a 55 amp converter and now when I took the panel apart I see that...

Would it be okay to run a suicide cord from my inverter into a wall outlet in my house to power one circuit and then just flip the breaker off that normally powers that circuit from the grid?

In the picture below I've drawn the two 540 watt solar panels I've been talking about. The first configuration would be better as far as less wire length and it would make it where my connections are under the panels where they can be protected. In the second configuration at the bottom of the...

Do any of you guys have one of these or any experience with them? Just thought I'd put it on here and see what people think. https://a.aliexpress.com/_mPczTN5

Is there such a thing as having too much power for your loads and your battery? I was just wondering what happens if you have so much power coming in from your array that your battery is constantly at 100%. Would that be bad for the battery to never get discharged?

I have this little mppt charge controller and it only shows two amps of output. My battery is at 91% charge. But, when I check the amperage coming directly from the solar panel, it is 4 amps. Does anyone have any idea what's going on? By the way, the picture of the display on the mppt did not...

Wanting to build my own battery but there's not a lot of info on it that I can find. I watched a couple of Will's videos and it looks like he's just setting up the cells in series throwing on a BMS and sitting it all on a metal rack. Is it that simple? Does anybody know of any resources on this...

I've been struggling with this for a long time. I can add up all the Watts that everything normally takes in my house but I don't know what the surges are or anything like that so, just now I got on the internet and asked it something like how much inverter do I need for a 1400 square foot all...

I have this system in my old camper. Never had a problem charging my Lifepo4 because I also have solar power. I have a new inverter that I wrote about in a different post and I was trying to figure out how to wire it in. I took the panel cover off and realized, the fan in the converter wasn't...

I'm new to this like I have been saying but, how is it that I only have 400 watts of panels but when I look at the mppt it is telling me that sometimes it's going clear up to 420 Watts or so coming in?

I have a couple of big panels that are basically 4x8 ft. I'm going to be making my own L brackets out of aluminum angle and I was wondering how many mounting points you guys would recommend. You think six mounting points per panel is good enough?

I'm new here so, hello everyone. I have a 100 watt Renogy suitcase with the 20 amp Voyager charge controller and I'm wondering how I can connect the same solar panel suitcase that does not have a charger. I know that the 20 amp charger will take the additional 100 Watts that I'm wanting to add...

Hey guys, I was wondering if any of you know of a remote control that will work with this inverter. Furion is very vague.

The battery says it's a 100% And The mppt has stopped charging like it should but, the cells never seem to actually be exactly the same voltage. Is this a problem?

I was checking this out when I noticed, it seems a bit low in voltage output for a 48v battery. I'm a bit new to this so, I thought I'd ask what you guys think.

So, I have the solar panels mounted for my swamp cooler project and I have the PV cables running along the house and down to the window where the swamp cooler will be installed and I will need to put the components (inverter, SCC and battery) Under or beside the mouth of the swamp cooler that...

If I have four of these panels: And the 35 amp model of this mppt: Can I link all the panels in series? The charger says that it's a Max open circuit voltage of 100 volts. The panel say that they're 24.3 VOC. Do you guys think that's cutting it too close? It seems to me like it would work but I...

I am being offered a used setup here locally but, it's confusing to me. It is a pair of grow watt 5000 es inverters that were purchased from signature solar so they're supposed to be some kind of a US model but, the sticker on them says that they are 230 volts. The lady who is selling them says...

Is this ok or???

https://www.alibaba.com/x/xC0kHbW?ck=pdp I don't know how to use alibaba. It's really new to me. I don't know how to view the seller ratings. What do you guys make of this? Can someone check it out and tell me what you think? I think it's a scam but, who knows?

I was thinking about buying one of these batteries and Will Prowse says they're built well but, it doesn't look like they have a bluetooth app. Is this true? If so, how are people reading their battery cells and balancing their batteries or setting parameters or anything. I'm totally new to...

This little charge controller has been working great for a couple of years. Today, I went out to my camper and saw that my battery was dead so I took a look at the screen on this charger and it was totally blank. I have had that happen before so I unplugged the solar input cables from the PV...

What do you guys think? https://a.aliexpress.com/_ms7nSPh

The converter has a Grounding lug on the case. Where would I ground it in a slide in overhead teuck camper? The Grounding buss in the breaker panel or?? Thanks

This is my heat pump (bottom) I run a swamp cooler in the summer because I can make my house much colder with it and still have a very low electric bill but, I will need this heat pump sometimes in the winter. I have a wood stove but, I need the heat pump in the night and on certain occasions...

I have the system mocked up. Two 540 watt panels on the roof right in direct sun, a Sensata Dimensions brand 1500 watt inverter that says that it can surge to 2,800w, one lifepo4 100 amp hour battery and the Y and H solar charge controller. Everything else is working fine but, when I try to plug...

What do you guys think of this: https://a.aliexpress.com/_mqgOg3Z

If I bought the inverter shown below, what all switches and breakers (sizes and types) would I need for it? Does anyone make a kit? Is there anything else that I'm missing here that might be another expense? I've been comparing this inverter to the eg4 6000 xp. It seems to come with the breakers...

I wanted to install a system in Idaho that would allow me to generate most of my power but still have a little bit of incoming power from the grid to handle it if my system can't keep up with my loads. I was talking with a friend earlier and he told me that I cannot use a hybrid inverter even in...

Buy, build, steal? Wondering what the least expensive but, still workable way to get 48v lifepo4 batteries is. I see Server rack batteries all the time but they seem like they're about twice as much as a regular battery. What would be the downfall? Lack of communication? Don't really need...

What are you guys think of this inverter paired with 20 of these solar panels? Any of you guys have this inverter or know what the original manufacturer is? Quality?

Hello everyone. I'm kind of new to solar. All I've done so far is put a small system in my truck camper. Now I've caught the solar bug and I'm looking to put some on my house. I was looking at a Powmr brand inverter and what I don't understand is, how is it wired to your breaker panel? I only...

I could add more panels if I get a 24v inverter and wire my 2 100a bms batteries in series but when I only had a single 12v 100a bms battery, it wouldn't handle the surge when my swamp cooler started up. This led me to a question. Do 2 12v 100a BMS lifepo4 batteries in parallel to a 12v...

Still having trouble deciding on an inverter. What do you guys think of this one?https://clouddisk.alibaba.com/file/preview.htm?appkey=OneChat&id=3532982589&parentId=3340529043&secOperateAliId=MC1IDX1I3KnLDO90taC4TTLilLOtAoiWe1bNbVGpUU2Kk-phTRoTL3mB_u1nmX26MyaxZ-d&scene=1
