  • Every other panel on the array is clear of snow, rest are covered - is my theory correct?

    My 185w panels are set up as 2S3P, I noticed after the last snow a week ago that every other panel had snow on it, which I thought was odd but didnt think any more about it. This morning I noticed it again after another light snow. Walking out and checking the clear panel, I noted it was the...
  • Turbine back up in the air

    After I built this F&P turbine and tested it, I took it down to make some improvements, mainly on the weatherproofing as the magnets will rust quickly if not well protected. I haven't wired it into the controller yet as the barn batteries are quite dead from sitting, but I will be getting deep...
  • Noobie question about AGM battery capacity vs discharge levels -

    Still testing this system but using it (lightly) as well. Last night I ran a 90 watt load for 14 hrs, from the time PV charging stopped to the time it started this morning. My SCC indicated 26 battery volts when I started, and this morning was 24.8 v. Using my limited math skills, I get 1260...
  • Battery equalization issue - AGM batteries

    OK, I thought I had this problem figured out, but I am getting the same results after the fix, so I am asking the help of forum members here. Quick Backstory - I converted my system to 24v from 12v when I moved it into the house, and noticed a small battery imbalance between the two AGM 200ah...
  • Experiences with Y connectors - Anyone ever over amped one?

    Been reading these forums for about a year now, I do not recall seeing anyone post about overloading a Y connector. I know they are supposed to be nominally "30 amp" capable, but what happens if they are overloaded to 40 amps? or more? I would think some noobies would have accidentally done...
  • Victron balancer - Proper wiring for 24v 2S2P?

    Finally ready to hook my system back up after incorporating two more batteries, and I upgraded to a balancer that should handle this. The manual shows what looks to me like some odd wiring in the common zone as it shows the wires connecting the commons of all the series of batteries. I have...
  • self consumption power or power drain in system?

    Hello, Over the past few days I have noticed a strange (to me) occurrence. I have just installed a Epever Tracer 6415 AN controller and an MT-50 remote programming unit with it. It is hooked to 740w of panels (for now) and charges two 12v renogy AGM batteries in series., 24v. Since it has been...
  • Series parallel question - four 200ah AGM 12v batteries

    As my system is growing, I am in the process of adding two more AGM batteries to increase storage. I did not buy them all at the same time. I have two in series now and plan on adding two more. The two I have were bought in August 2022, and in October 2022, and have been very lightly used until...
  • Epever Tracer AN series question regarding load terminal

    Here is what I am attempting, maybe its completely out of line, hopefully not - I want to add a DC 12-24v LED reading lamp to the load terminals of the SCC. (Epever Tracer 6415, I assume most of the AN series is similar). Pressing the select button on the SCC turns on/off this port, and the...
  • EPEVER tracer 6415 backlight/ battery ah settings

    Been using the 6415AN Tracer with the MT-50 remote and has been working very well, but I find I would like to see the monitors without using a flashlight, so I changed the backlight setting in the MT-50 to "000" (after trying "999" which didnt work) , This works but only on the SCC, the...
  • Issue with hybrid wind-solar setup

    I have been adding a solar component to my wind turbine for the purpose of keeping the batteries charged when we have some non-windy days. (Background - Two 100w solar panels feeding two parallel 12v batteries in parallel with a homebuilt F&P turbine) - I am getting some unexpected overcharging...
  • Sparking at hookup - parallel batteries - something seems wrong

    Hello all, been fighting with a strange issue this week. Just received the second battery (SLA 12v 200ah) and was hooking them up in parallel as I did not have enough storage in this system (and I still need more batteries), I finished the connections and was a bit surprised to get a nasty...
  • quick turbine orientation question

    Due the the prevalence of southeaster's this year, I decided to lock the turbine aiming into the wind at SSE. This location only gets wind from the South, or from the North. My question is this - If the wind switches direction, (comes from the North), the turbine will spin in reverse rotation...
  • AGM equalized voltage question

    I have completed moving my system into the garage at the house, from outside in the barn, due to the cold weather. I have changed the setup slightly to accomodate a 24v system. I had two 200Ah batteries in parallel, now arranging in serial. They have been sitting since Nov 3. Checking the...
  • Need an idea on charge controllers

    working on planning a large system in mid florida and wondering what the basic setup for controllers is for this when the amps need to be high. Maybe someone else with miners can give me some pointers. I am looking at 40kw /per day usage, likely a 48v system, and an array of 400 or 500w...
  • Epever Tracer - anyone ever gotten the Epever software to work under WINE (Ubuntu laptop)?

    Just wondering if anyone has tried to install the Epever support software on a linux laptop, all they offer is winXP, Win7, and Win10, and some android apps. I would like to use my old linux laptop in conjunction with WINE on Ubuntu to work with the Tracer for some logging and programming.
  • Theoretical question on series panels used at night

    I have noticed during a full moon that my SCC registers around 2 volts coming in from the panels, which led my friend asking an interesting question, Why not have a large series of panels, enough to bring that voltage up into the charging range (lets say 12v system for simplicity). Obviously...
  • Stalling Issue on turbine

    Finally got a weekend with good wind to experiment with the turbine, and was able to confirm its stalling under load. I disconnected the cables and the stiff breeze immediately started the turbine spinning up. Reconnecting them slowed it right down and stalled it. So I need to prevent the...
  • Voltmeter at SCC inputs?

    Is it ok to wire a small digital voltmeter to the input terminals (pos/neg) of my Tracer controller? I would like to see the incoming voltage of the panels as it enters the controller and I would want one at the combiner box at the array. Using those I could always see my voltage drop across...
  • Running time on inverter seems way too short - testing

    I ran a test of my initial system yesterday with a new Renogy 200ah battery (fully charged), it is supposed to run 10 hrs at 10 amp load to 50% capacity according to the chart they supplied. I hooked up a small (4000btu) a/c window unit to it, turned off the solar, and ran it through a borrowed...
  • Newbie setup for backup power for freezer

    Here is all I want to do - Run 1 chest freezer overnight, or if not possible, run the freezer during the day and let it coast overnight. We have blackouts often, 3 weeks was the longest, and cost of running a genny that long was enormous, even when gas was $1.99. What I have - eight 100w...
  • Please explain FV/time in this chart

    Good day all - Newbie to this forum - Recently I purchased a 200ah Renogy SLA to experiment with on my micro solar plant (4 100w panels, 2 in series then parallel) into a 40a mppt SCC and final output into a 2000w inverter. I was wondering about the initial charge requirements, and nothing came...
  • Transfer switch question - basic

    Good day all! I was wondering if I can connect a transfer switch to a subpanel and not the main panel? I have a basement apartment (no longer used) that has a subpanel run off the main panel up in the master bedroom. Since the solar feeds into the garage, (where the subpanel is), it seems...
  • Question about ambiguity in Victron balancer installation notes

    Good Morning frenz, I have a question about the instructions given in my Victron 24v Balancer The system is 24v with 2s2p arrangement of 12v 200ah AGM batteries. The Victron manual lists these notes for wiring the balancer in. (2) In case of series-parallel connection, the midpoint...
  • Question about charging SLA with Renogy Rover Elite 40A

    The manual for this SCC lists 4 stage charging, Bulk, Boost, Float, and Equalization. Equalization is carried out every 28 days (according to the manual) and it "overcharges the batteries for a controlled period of time" , "which gasifies the battery electrolyte". I have two 200 Ah SLA...
  • Panel defect - Schuco 185w - can this be mitigated?

    I recently found a deal on some used Schuco 185w panels so I picked them up to possibly use in my array. After getting the info on the panels, I found that they were probably removed due to the defect mentioned below - Is this an issue I may be able to mitigate myself? I am aware of the SanTan...
