I’m looking at a setup for my new house in which the meter feeds into a service entrance rated 200 amp automatic transfer switch designed for use with a generator but with solar on the other side rather than a generator. The ATS would sit between the mains inputs and the main panel so this is...

I have a customer that bought these batteries and I am having a very hard time getting reliable information about the specs on this battery. The information on Amazon is conflicting and I have had little to no help getting the specs for these batteries for the Victron Smart Shunt settings. I...

I have been having an issue with the Bypass function on my Growatt SPF 3000TL LVM-24P Inverter. I have provided a link to the videos showing the errors and settings. One is the error itself and one is a vid of the settings. Please take a look and help me solve this problem. I have tried a lot...

Just wanted to post some pics of my latest build. A 2004 Holiday Rambler Neptune Class A Here are the details. 4000 watt solar array Custom aluminum solar racking with steel coated safety tension cables. (2) EG4 - 100ah 48 volt rack mounted batteries. 10240 wh capacity Growatt SPF 5000 US...

Here are some details of my system. I have two SmartSolar charge controllers feeding one DIY battery. Charge controller 1 SmartSolar 150/45 - Fed by a 1200 watt array on the roof of the camper. Charge controller 2 SmartSolar 100/30 - Fed by a 500 watt ground deploy array Battery Bank 6014 wh...

I build off grid mobile solar systems for a living for RVs, Vans, Skoolies and Tiny homes. You don't need a structural engineering report for these types of installations. However, I have decided to take my own home off grid and it is in town and I will do all the work myself. The city I live...

I run a facebook group dedicated to teaching solar. Typically i advice against mixing solar panels because most of the time the efficiency losses are to high. So i will advice multiple charge controllers. However this diagram was posted on my Facebook group. (This is NOT my design). If you...

Older converter compatibility with SOK Lithium 206ah battery I am installing a 206ah Lithium battery in on old 1984 RV. It has a 7445 45 Amp 7400 Series Converter Charger. I am replacing two 78ah Lead batteries. Here are the specs on the DC Output of the converter/charger. DC Output - volts -...

I need the help of my peers on a Voltage Drop problem. Here is a run down of my system. 1200 watts of solar on the roof. 4000 watt AIMS inverter/charger 800ah (400 usable) of Renogy Deep Cycle Hybrid Gel batteries. (4800 usable wh) - Eight 100ah Batteries connected in parallel. 12 volt system...

I am about to begin a battery build. I have eight 280ah Lishen EVE Cells on the way. I am trying to decide if I should build two 280ah 12v battery packs or one 560 12v battery pack. The reason i am conflicted is the loads i am putting on this in regards to choosing the BMS. I have a completely...

How do i figure out how long it will take for a given solar array to charge a given battery bank. (What is the formula?) For instance if i have a 1200 watt array how long will it take to charge a 400 ah lithium battery bank. Or how long for a 250 watt array to charge a 100 ah battery bank

Hi Everyone, I’m John. Ive been studying solar for several 5 years now and just built my personal system in my Primetime Avenger LT 17BHS Travel Trailer although I have built for other people. I built a 1200 watt solar array in 6S 2P configuration with eight 100ah Deep Cycle Hybrid Gel...

I designed and built this system from scratch. I also custom built the slides for the additional solar panels. 1200 watts of Renogy 100 watt panels and in Series/Parallel, 800 ah of Deep Cycle Hybrid Gel batteries. (Yes i know, not Lithium but needed to save money somewhere) 4000 watt AIMS...

To help people understand battery capacity as it compares to different voltages. If you have a 400 ah - 12 volt battery bank then thats 400ah x 12v = 4800 wh If you have a 200 ah - 24 volt battery bank then thats 200ah x 24v = 4800 wh If you have a 100 ah - 48 volt battery bank then thats...

Im having a problem with this install. I am in the process of installing an 800 watt Renogy system. 8 - 100ah Deep Cycle Hybrid Gel Batteries (Wired in parallel) 8 - 100 watt Renogy panels (Wired in Parallel) 4000 watt Aims inverter/charger 150/100 Renogy Rover charge controller. The...
