I switched the cables to the solar breaker to 10 gauge since this photo. My question, do I need to earth ground the panels ( sinking an 8 foot ground in AZ cement like soil is no easy task). I have a long metal fence nearby that runs to a block wall is grounding to that a bad ideal?
We used to scoff at "Made in Japan" equating it with cheap stuff until it became a symbol of quality. You need to know a manufacturers reputation prior to buying if that's possible but the facts are the highest quality parts, batteries, electronic components and solar panels are mostly made in...
Your post provided a good tip on how to properly set a bolt into aluminum terminals. It was very clear and a good suggestion. Completely separately from that tip about bolt length and washers needed to get it perfect was the same point Will brought up to be paranoid when tightening that bolt as...
I found the same thing as Doug, some settings only “take” with the inverter switched off. I found once the charging or and other desired setting changes start you can switch the inverter back on and the settings hold. If using the software and you click something and they ask for the...
True but he had to keep trying to redirect the answers back to the simple question. I learn a ton from these conversations but have to admit they sometimes never quite directly answer the question or if they do you need to pull one nugget from nine replies. What if the first reply said, yes you...
Most countries including the US are probing the grids of other countries presumably to have the ability to disrupt power when that would be expedient. Password spraying is happening to the US grid by at least three countries as we speak. My first though was if there is a forced power grid...
I have two Renology 12v 200 amp gel batteries in series used with a 24v MPPSolar all-in one. The battery spec sheet shows a full charge at 12.8v or 25.6v for my two in series. They recommend to discharge to 50% or 12.1v/ 24.2v for my batteries. I have a hall effect meter. While bulk charging the...
I have a 24volt MPP. Its big and heavy and a bit loud. I have it as a home unit so it works for me. I love the simplicity, graphic display and the automatic transfer function. It will power a load with solar first, then battery, then utility, then back to solar if the PV watts start to exceed...
I am sure he would maintain the battery for an emergency with grid power but use the generator only when there is power outage to charge it up. A family member uses a CPAP and is just south of the Kincaid fire zone, and in the likely power outage zone. A good battery inverter combination is all...
On thing I found when deciding on series and or parallel using my 24v MPPSolar PIP is the manual shows 145v PV Max, 80 amps max. Yet at 125 v in my full series connection of four 250w panels it shuts down. If I parallel 4 panels (roughly 8 amps each) it won’t detect the panels (amps too high)...
Yep wrote it too quick from work, 8 cells, but the main point was how to find out how to assess the problem. No obvious swelling. I kept a cell meter 8 connection intact and could cycle through the voltages of the cells and they stayed voltage matched on occasional testing. I just put it aside...
Victron’s Battery Protect (mine is 12/24v 45amp) has mode a b c yet it is tough to find a simple definition of what they are used for or which to use with gel batteries anywhere in their included or online literature. A YouTube vid states I should use 6 mode “b” with AGM but I thought it was...
Yes, the depth of discharge vs number of cycles is a downward curve and you want to stay to the left side. But it’s not a steep slope past 50% and a single test of a battery to 70% DOD likely did not kill my battery. What’s interesting is how you decided the depth I reached. I went with voltage...
In a simple low cost shed system using 400 watt PV panel, a single 12 volt 200 amp gel battery, an EPEVER 30 amp charge controller, and a 2000 watt inverter you have low voltage disconnect on the charge controller and inverter that kicks in at 11.1v, way too low to prevent damage to the battery...
I have four 250 watt used San Tan Solar panels mounted on a side yard wall ($50 each). I get 100-400 watts of solar power depending on the season and time of day. I use a 24v MPP Solar all in one. It’s set up as an off grid power supply to one room in our home that draws 125 watts or so to run...
I got those fully charged voltage numbers of 25.6v from the Renology web site (attached). The specs for battery itself does state a charging voltage of 28.2v I thought that meant charge voltage must be higher than the battery voltage but did not understand that you could charge to 28.6v. So if a...
Send me pics and size specs I’ll give it a go. From experience in making parts a digital caliper (quite cheap) may be needed to measure the inside and outside diameters and lengths.
