Just installed (16) 450 watt Sungold panels at our off grid camp! Super pumped I got it done before the snowstorm too... It was freezing the day we installed them which made the aluminum staging planks super slick, but other than that, no complaints:) I checked power output towards the late...

I measured four separate strings at 197 volts giving me a total of 788 volts. I also installed them at the roof's 44 degree pitch. Last year at this time we had over 4 feet of snow, this year, 1" :ROFLMAO:

Just replied six of the questions, most of which I just said "Please reply with more specifics on your system" :unsure: :ROFLMAO: :ROFLMAO: A lot of the questions in that section are either very vague or extremely specific and obscure questions that I cannot help out with. Hopefully they reply...

Ok, Let me double check this one last time.... Inverter # 1 MPPT String 1 - 4 panels in series (176 Volts @ 10.2 amps) MPPT String 2 - 4 panels in series (176 Volts @ 10.2 amps) Inverter # 2 MPPT String 3 - 4 panels in series (176 Volts @ 10.2 amps) MPPT String 4 - 4 panels in series (176...

I will share this post with one of the EG4 techs that are here at this forum. In the meantime, I will leave the existing generator as is and not make any connections until I get a better sense of the architecture of the inverters. @EG4_Jarrett could you take a quick look over this post...

I may be waaaaay off here but had you thought about designing a "solar hot water heater" and running these lines into your outside tub? No need to use a power hungry hot tub when the sun can heat your water free of charge without taxing your solar power needs. Just a thought:)...

This setup would give me 24kw at the panel, 114kwh of back up power, and plenty of solar input. All for $43,507

The only reason I'm even considering off grid is because I don't like being at the mercy of the utility companies. Energy costs shouldn't be this expensive considering we have the resource to supply our own power from the sun, wind, and water. Don't want to get on a rant so I'll leave it at that lol

I am looking for the cable that connects a PC to the battery (LifePower4). The cable in the video is only for battery/inverter communication. Everywhere I've seen and instructions in the manual require a firmware update that can only be provided via connection to a PC. The cable needed to...

I happen to work with a mac, and found this video incredibly easy to follow along. Battery is now officially updated!

Re: "Alternatively, you can connect your generator to a separate battery charger and only use the generator to charge the batteries and leave the inverters on single duty of inverting the battery power to AC. This also eliminates passing possibly dirty power from the generator to the house...

I'm looking into using 4 EG4 6000XP's in parallel vs 2 KPV's also. Due to the fact that I don't need hybrid, 6K XP's might be a better fit. Plus I already have an extra one from my camp installation that I can use so I would only. need to buy 3.

Is it possible the "UL" sticker is inside the battery? I know it's dumb, but you could have proof of the certification if it were there. I have four of these batteries and never saw a UL sticker on them but I recall watching a video where someone opened them up and the UL stickers were inside....

Ok....Don't get mad at me.... lol I finally problem solved my problem, and it wasn't the battery wake-up settings on the inverter. I was able to identify it by checking all of the voltages and found my panels were not providing any power whatsoever even on sunny days. My issue involved the TIGO...

I get it... I agree, I need to 100% focus on the demand aspect first then figure out everything else. Otherwise it's a big waste of time! I like the idea of using 3-4 6K XP's. They are stackable, meant for off grid use, and I am already familiar with them. Again, I need to back and figure out...

What is the efficiency lost for btu output on lower temps when using a heat pump? I was always told here in Maine that although a heat pump can provide heat, it is not recommend as a primary source of heat simply because the technology lacks the ability to be efficient sources of heat due to low...

I haven't heard of that company before. I would stick to some of the more reputable companies, signature solar, shop solar kits, current connected.

Hello Zapper, Thanks for checking back in. I ended up deciding to only put into service one 6k inverter. I ran into bigger issues with my system that forced me to only install one inverter at this time. Namely, I didn't have enough room on my roof for 32 450 watt panels which was what I was...

I've had six panels on my roof, same angle, same placement, and haven't had any issues with the snow:0

I am somewhat familiar, thank you! I would like to tie the +/- power leads from the server rack bus bars to a DC breaker, and from that to the heat pump. #10AWG should be plenty considering the distance will be less than 15' from the battery bank.

Typically its best, if you're able to, provide a link to a manual for your components FYI. I'm not sure what is called for on your inverter but it is usually a good practice to install a D/C breaker or isolator between the solar array and the MPPT charge controller or inverter if it is an...

You might not be getting a reply because the question isn't relating to solar. If you were wondering about the best pressure cooker to use with an off grid solar system, you might get better results ?

Ok. Thanks for clarifying! From I can understand here, the problem doesn't lie in the amount of power coming from the solar array. It comes from the amount of power drawn from the inverter/battery bank? Also, I thought there was a minimum threshold on the PV input needed for an inverter to use...

Hello All, I am looking for some suggestions for a design/build for a whole house off-grid system with potentially solar/DC powered cooling systems. We recently installed an EG4 6k inverter with LifePower4 battery storage at our camp and really like how the system has performed so far. If I had...

I've been running into this same issue myself tying in (16) 450w panels into two EG4 6000XP inverters in parallel. I chatted with tech support Friday and they had suggested I separate my (16) 450w panels into four quad groups and bring two strings into each inverter. That would bring in roughly...

I noticed that too, is there a different section for buying/selling items?

I just found your document on "Grounding Basics" @FilterGuy. I'll look this over and let you know if I have more questions, I'm pretty sure my answer is in this document lol. Thank you for posting this!!!

Other than allowing the solar panels to help it charge the battery bank to 100% no. The camp is off grid and I'm not sure if introducing another power source such as a gas powered generator/trickle charger would be safe. It sounds like the inverter isn't sending the signal to the generator. Or...

Thank you @EG4_Jarrett !! Your message came across perfect too:) I will look this over and let you know what i end up doing.

Absolutely! I plan to build a timber frame structure, facing the south. Perhaps a shed style roof to allow good winter sun rays to heat the main area. Again, starting from scratch here. The main reason we are even doing this is because we need to get out of the city... Where we currently live is...
