    Saving your charge controller with a Battery Protect and a PV cut-off Solenoid

    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...

    Finding the bad lifepo4 cell

    I have 8 of the generic used Chinese lifepo4 100-amp cells assembled into a 24v battery with a Daly 40 amp BMS. When charging the battery with my MPP Solar with correct lifepo4 settings I smelled a chemical fume right at the start of the charge, so I quickly switched them off. I checked the bus...

    Should off grid stay off the grid to have a valid backup.

    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...

    https://www.amazon.com/gp/product/B01KN7K48W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I bought two of these 6-months ago and noted that they are $100 off or $350 for a 200amp battery right now on Amazon with free shipping for Prime. I tested mine with a shunt and at 75% discharge it hit...

    24 Volt MPP "AGM/GEL" Setting is too high

    I wanted to simply set the PIP charge settings for my two 200amp Renology Gel batteries to the "AGM/GEL" setting and let it automate the charge. Unfortunately their default is to bulk charge at 28.2v then float at 27.0v. If left to finish a charge cycle on the PIP "AGM/Gel" setting my rested...

    Saggy Voltage

    I’m using a Victon Battery Protect with Gel 200 amp batteries two in series with a 24v MPPSolar all-in-one (PIP). Let’s say I want to have the Victron kick in at 23.6v to avoid an over discharge below 30% (setting 7A). The voltage will sag on a 900 watt load while using a portable AC and trip...

    Is over charging a gel battery OK in order to get a resting state full charge

    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...

    Victron Battery Protect AGM settings

    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...

    One room solar

    I live in the desert and wanted a be able to run a small one room portable AC at 900 watts continuously during a power outage. I pretty much used Will’s videos to guide me all the way. MppSolar 24v all-in-one, Daly BMS, 80 amp circuit breaker to the battery, lifepo4 100 ampHour Chinese sourced...
