Hi. I have a small problem with my car's battery not keeping its charge because I am not driving the car as much, plus, since my place of employment is closer to my house I only drive 1 mile each way. So, I am guessing that the car is not on long enough to keep the battery charged for long. I...

Is it possible to change the device name for the Bluetti EB3A. I'd like it to display something else, or nothing at all, if possible. TIA.

I am searching this forum and other sites for a battery monitor that includes the running and/or time remaining displayed whenever I add something to my lithium battery, like you get on power stations. I know I've seen this some years ago in someone's custom van tour where they had a small...

Does anyone have any experience with the "Pecron E600LFP Power Station 614Wh 1200W" system? I'd like to know the bad and good about it because I have decided to get one. Please share your thoughts and experiences with this system, thanks.

I've been working on an updated run-time calculator and get different results, and I believe that I need to factor in the Wh also. But that may be for another story/topic. Anyway. I've seen battery watt-hours (Wh), (like 268, 360, 400, 517, 700 Wh's) with build-in 600-watt inverters. Using...

I do not understand this and I read how people return the SCC if it is a positive and not a negative. 1. What is the recommended setup, pos or neg? 2. What is the best or preferred one, pos or neg? 3. Which SCC are affected by this (requirement?) PWM or MPPT or Both? 4. How do I test/determine...

I am searching around but this time would like to know what (true, not fake or simulated) MPPT SCC would anyone recommend for this panel. DOKIO 150w Solar Panel Kit Portable Folding Monocrystalline Include Solar Charge Controller and PV Cable for 12v Battery Charging Camper RV Van -...

I was wondering, how do you calculate the angles for rigging up a solar panel for the maximum sun coverage? I have seen numbers like 20 to 45 degrees but I don't know if those are correct angle numbers. What I'd like to do is rig some wood or metal poles and draw the angle degrees on them and...

Ok. I am searching for another 150 watt solar panel, and I came up with the one below. The price is not bad, $136 w/out a scc. However, something odd about it. If you look at the specs (in the photo I show) the math does not add up to the 150 watt they advertise, unless I am doing something...

I am just curious. Has anyone built their own fuse box? I was shopping around on amazon and ebay, searching for a cheap 4 to 6 fuse setup but man they are expansive. Today I thought, maybe I could build one if it wouldn't be as expansive than purchasing one. If you built one, how did you do...

Hi, I am building a small solar system for my minivan and wanted to share my experience here as I build it. So far I have ordered a 150w solar panel and Battery. (A charge controller is next. I suppose some wires (not sure of size yet) and fuses and small fuse-block may be needed.) ** Solar...

** BATTERY ** LiFeP04 Lithium Iron Phosphate 20/30 Ah I am trying to build a starter solar/battery system for my minivan. To keep the weight down I would prefer a Lithium battery but they are expansive. (A 100Ah lead/AGM battery is heavy and the risk of damage during shipping is scary) Now...

So, I have several batteries laying around and I don't know their amp-hour rating. I would also like to calculate its Wh (watt-hour) as well. I assume you have to know the Volts and then the Amps to calculate the Ah and Wh. I am not sure if it is a Calculation or steps to perform to arrive at a...

/rant on/ ok, i had to ask this question because i could not search for it in a way that would not drive me any crazier than i have been so far. I am building a calculator for windows and android, and I have plans for various features not found in any other app, and i want to offer it here...

just here saying, hello! and have a great day!
