Do UL listed 12 or 24 volt batteries exist? So far the only UL listed batteries I've seen are 48 volt.

My county has a one size fits all permitting process you have to use whether or not you have a large roof-top grid-tie system or small off-grid ground mount. I was wondering if anyone lives in a county (or other AHJ), that has a simple, straight-forward permitting process for off-grid. I'm...

I just noticed that Current Connected lists a new version of the 48v Multiplus-II 3000VA Inverter as UL 1741 Certified. Is this a mistake or did the 48v Multiplus-II finally get certified? I didn't see any updates about it on Victron's website.

I'm designing a small solar system that will supply continuous power to a generator transfer switch in my garage for 6 months out of the year and for the other 6 months will be used infrequently(as much as sunshine allows). I was wondering if it makes sense to connect this system to the...

I'm looking to get some dc5521 adapters so I can run my router off of DC power. I'm having trouble figuring out what size plug my router has so I can select the correct adapter. Any tips on how to figure this out? Also, any recommendations for where to buy the adapters?

As I've been doing research for a DIY system, it seems like everything I want to do needs to be permitted and requires UL Listed panels. However, most of the consumer oriented panels from vendors like NewPowa, Renogy, BougeRV, etc. are not UL-Listed, so what are people using these for?

Most ground mounts I see send DC power some distance back to the house or garage where the batteries are stored. But is there any advantage to doing this versus building some kind of mini-shed under or around the panels to hold the batteries and inverter and then sending AC power back to the...

I'm designing a system and have space for 2-4 panels. I would like to get some UL listed panels, but so far all the panels I've found have a minimum order if at least 6. Does anyone know of a vendor that will ship small quantities of UL listed panels?

Is there a difference in shade that comes from the clouds vs shade that comes from a building (or tree) in how it affects the performance of solar panels?

I've been exchanging emails with my county permit office trying to get a list of requirements for solar installs. So far, they've only provided me with the requirements for panel offsets for the top and edge of the roofs. Is it common for an AHJ to have written requirements (e.g. must have ul...

I'm looking into purchasing a Victron Multiplus II along with a Victron MPPT and Lynx distrubutor. If I pair these with a server rack battery, like the EG4 LifePower4, do I still need to add a Victron shunt to the system (e.g Lynx Shunt or Smart Shunt)? Or do server rack batteries already...

Hi, I am interested in installing an off-grid solar system on my shed, so I put together a draft plan to help myself learn about solar panels and system components. I would appreciate feedback and tips on my design so I can help make the system better and help myself learn more. Also, I am a...

I have a shed with roof faces measuring 54 in. tall by 98 in. across This turns out to be somewhat of an unfortunate size, because I'm finding a lot of panels that are just a few inches to big to fit on the roof. One example of this are the 200w Newpowa panels, which are 55.28 x 27.76 inches...

When an inverter is listed as having 90% efficiency what does this actually measure? Is it the efficiency when outputting the maximum amount of power or does it mean 90% efficiency for all loads?

I was strongly considering purchasing an Ecoflow Delta, but I'm having second thoughts now due to the NCM battery chemistry. I'm mostly concerned about the safety of the NCM batteries, because I know LiFePO4 batteries are safer. I don't know if I'm just being paranoid because I know someone...

I have an outlet (powering a refrigerator and cell phone booster) in my home that shares a wall with my garage that seems like it would be very easy to connect to a solar inverter if I had one in my garage. Is this something that can be done safely? If so, what's the best way to do it? Does...
