Because of constraints I am flat mounting my panels in two arrays, but not exactly flat. I can't tilt them south but will have to tilt them east or west to give the best chance of water running off them after a rain. The simple least expensive method gives me a tilt of .8 degree east or...

I have a string of 14 panels 7 series 2P that I am planning the mounting of presently. 10 will be mounted 3 degrees tilted east for drainage. ( I understand that this is less than ideal but it's how they will be mounted). The remaining 4 of that string are in a place that they could be...

I’m leaning towards trying to do what is pictured below with my pair of xw pro inverters. I didn’t understand that this was an option when I purchased them. However it would shorten the payback period of my investment. But then in the same XW Pro Self-supply and Export Limiting Solution...

What would you need to do actual comparison testing of the output of some solar panels mounted in different angles and configurations? Before I commit to permanently mounting my panels in any one configuration I would like to be able to measure the difference in output over the course of a day...

I’m using 2 xw pro’s and two eg4 100 charge controllers. I have often read in posts that these charge controllers and inverter chargers are loud when operating. Is there any way to quantify that? I realize loud is subjective. However can someone who has similar equipment give me a better...

I’m confused. I have an XW Pro that I am trying to figure out how to use and get the most out of it. . I can’t sell to the grid in my location it's not allowed and at this point I’m not intending to go off grid. The main function of the system I am assembling is to backup a couple of freezers...

How likely would I be to smoke a eg4 Mppt -48 charge controller if the total isc is one amp more than the max rating on the data sheet? Is the 22 amps max on the data sheet a hard stopping point or is it a firm suggestion. In the desert outside of Phoenix. See 116 days in summer. 19 F at...

My equipment: 2 arrays, distributed on 3 shipping containers, none of which is a residence, in a particularly hot part of the Sonoran desert. This year, weeks possibly months of 115 with a single day high of 124. Electronics as a rule don’t fare well in these extreme temperatures. Some do...

New to this. My first attempt. I have eg4 48-100 mppt charge controllers. They apparently talk to their power pro batteries. But, their manual warns not to use that function when using their inverters because of communications issues of both the charge controller and the inverters choosing to...

I am considering buying a used xwpro. For now it is going to be used off grid. Do I have any options cheaper than the the insight home for setting parameters, etc. Can I talk to it with a laptop?

My equipment. 3 SOK budget server batteries no external communication Schneider xw-pro only speaks Schneiderese. 2 EG4 charge controllers. Talk but not to the other pieces. My solar equipment lacks compatible communications. The batteries have BT communication limited to the bms for...

Watched the Current Connected video. Couldn't really tell how thick the uprights in the rack are without powder coat. Are they .090 or thicker? Or are they 1/16th. Was thinking of using one for the core of a project.

I bought some used panels which came with Unirack rails and the L and brackets to mount them pictured below. My plan is to glue them to the steel top of my shipping containers after removing the paint then coat them and the bare steel with self leveling rv sealant or rubberized roof paint for...

I’m referring to the physical dimensions of server rack batteries that exist among the variety of manufacturers. Will one brand of server rack battery physically fit in a different brand of battery rack? Is there a standard mounting width? Server rack batteries in general physically fit in an...

Which readily available battery chemistry has the best prospects of a long life when used in the desert with average temperatures of 110 to 115 degrees F. What extra precautions should I take to extend the life of the batteries operated at those temperatures. Assuming 24 volt and 200 to 400Ah...

I have 28 used sharp 235 volt panels. The label on the panels reads thus: Maximum power 235 watt open circuit voltage 37V short circuit current 8.6A Rated voltage 30V Rated current 7.84 A Maximum system voltage 600 v Maximum series fuse 15 amps I am making 4 strings of 7 panels each then...

I live in the desert. 104 today but I see many 111-116 days in the summer when it warms up. I'd like to put my batteries in a shipping container outside. If I shade it with solar panels but do not insulate it, pull in outside air with a ventilation fan, I can get the temperature down to about 5...

I hope I have successfully designed a small expandable backup system for my property located in the desert. Very hot, lots of sun. I’d like to get an opinion on what I am planning before I spend more money buying the remaining equipment that I have decided on. I presently have 6580 watts...

I have a Conext XW PRO 6.8KW ordered. When I get it installed along with everything else I will need batteries that can make full use of it’s features. Especially it’s ability to deal with starting currents of larger induction motors. I intend to test that feature, perhaps often. The flyer...

Anyone know if it exhausts hot air out the bottom or if it exhausts it out the top? I looked through the literature but did not find an answer. I am guessing the hot exhaust is out the screens at the upper sides but would like to know for certain. Not certain if the screens are intakes or...

A little background. I‘m located in the Sonoran desert. Can be continually 115-16 in the summer with lows in the high 80’s Low 90’s for weeks on end. Winter temps typically run low 30’s with highs in the high sixties. It’s also windy here. 45 mph winds aren’t that uncommon. Not a lot of...

I was reading through the manual on the EG4 power pro battery. it states: “Do NOT mix EG4® WallMount 280Ah batteries with any non-280Ah lithium batteries. This will void your warranty.” I bought a pair of these for my system. When I choose to expand my battery system down the road what are...

Below is a photo of the display of a EG4 PowerPro battery that I have in storage. SOC on the lcd display shows 55%. At the same time there are 3 led’s in a separate display next to the lcd with the 25%, 50%,75% led’s illuminated. This display is not mentioned in the literature and there is no...
