  • Out of town for a few days, should I disconnect some panels?

    Heading out of town for work for 5 days. I'm running a 2.4kw solar array wired in 4p6s. We are seeing record heat and sunshine this entire time. Thinking about disconnecting a couple of strings while out. My offgrid log cabin doesn't use much power while I'm away. Just need enough to keep...
  • Did I get two bad chins?

    TLDR; new chins 200ah in parallel after a couple of partly sunny days have charged from 13.1v to 13.2v. Ok so I got a couple of new chins 200ah batteries from Amazon a couple of days ago. They were both at 13.1v out of the box. I have a new renogy rover 60amp CC and set the user settings to...
  • Spinoff from house burning LFP vs AGM vs Lead Acid - Why not just run the older tried and true stuff?

    I know LFP is the new norm and I am running 4 Chins 12v 200ah in series for my 48v offgrid system powering my log cabin where I'm living. Very happy with the performance, but pretty shook up about this latest incident. I also have 8 Renogy 12v 200ah AGMs in my shop doing basically nothing. I...
  • Renogy 48v inverter has 30v AC between N-G

    Unit has been in operation powering my small offgrid log cabin for 2 years. I was doing some maintenance and discovered the inverter has 40v AC between the Neutral AC output and the ground screw on the case. This is with the inverter connected to ONLY the batteries. No MPPT, no AC input, no...
  • How low of voltage for Renogy AGM batteries?

    I have 8 Renogy 200ah 12V AGM batteries wired up to the Renogy 48V inverter with 2.1kw of Renogy panels. Powering my offgrid log cabin that I live in during construction. How low of voltage should I let these AGMs get too? We've had a lot of snow lately in Northern Colorado. I typically...
  • Unexpectant disadvantage converting from 12v to 48v??

    I live full time offgrid on Storm Mountain CO while building my log cabin. Been running the following 12v system with great luck: 8 Renogy 200ah AGMs in parallel, 40amp Renogy controller, 2000w Renogy inverter/charger and 9 100w Renogy panels in parallel. The batteries are less than 6 months...
  • Recommend me couple of 200ah Lithium batteries for my backup system

    Just as the title says, but let me explain my setup: I have lived 100% offgrid miles from the grid for 6 years in a small log cabin. The cabin is 100% operational meaning it has all the normal appliances, but the kitchen stove, dryer, water heater, etc run on Propane. My typical electrical...
  • Portable Generator to power offgrid cabin to NEC 2020

    I built an offgrid log cabin that is currently powered by non-listed solar. Miles from the nearest utility and will NEVER be 'on grid'. This has been a long process and I'm about ready for the final inspection which includes electrical. Rough electrical is done. All Solar-related equipment...
