Check this out, a new LiFePO4 cell giga plnt in the US:

I thought it would be easy to find some nearly square solar panels. Having trouble finding many. I have space for to panels, One max size 42" x 30" One 42" x 36" Anyone had success with any particular brand model of Solar Panels that are Dimensionally Square ? [Solar Panels will...

What happens in a LiFePO4 12v battery with a simple BMS if you CC charge it to an absorb voltageof 14.2 volts and hold that voltage continuously ? I believe that a lead acid battery generates H2 gas and heat when float charged at its oprimum float voltage continuously.

Here's a much nicer DC-DC battery charger. Higher solar input voltage. Custom charging voltages user settable. This one looks good to me so far. https://enerdrive.com.au/product/12v-40a-dc2dc-battery-charger/ What do you all think. Any experience with it ? Where to buy in US ?

Here's some good advice from some respected Mobile Electrical system persons (Dennis Wieske and Mike Sokol) regarding building your own LiFePO4 battery from individual LiFePO4 cells. (View minutes 57.35-59.52 of this youtube video) .

Dennis Wieske (Progressive Dynamics) discussed with Mike Sokol (RV Electric) use of Progressive Dynamics Converters to charge LiFePO4 batteries. -This discussion reveals a change in the Progressive Dynamics PD91**ALV converter design currently in progress to change the converter from a one stage...

I kinda' like these Combiner Boxes by Watts 247. Will did a youtube video on their features.

New approach to setting SCC voltages for LiFePO4 battery. I came across this You Tube channel, 'Off-Grid Garage' and have watched several of the videos there. I discovered this info. Its new thinking for me. https://www.youtube.com/watch?v=6vTaCkTVl7I Armed with this bandwidth concept between...

Has anyone experience using the DC Home Renogy app with Renogy DCC50S & BT2 devices ? The 'Renogy BT' app is no longer supported by Renogy. The DC Home app Seller is Renogy Suzho Co, Ltd. (China).

Looking for comment, experience, recommendations for use of a BMK with a MSH1230 M inverter. Any tribal knowledge out here ?

Is it possible to use one shunt with two battery monitors ? Why or why not ? Hope to get technical answers, not just reference to mfgr text saying yes or no.

Is there a public copy of this UL standard available or a discussion of its scope and requirements ?

Make sure your inverter is UL 458 listed. https://standardscatalog.ul.com/standards/en/standard_458_6

I would like to use a Blue Sea 7622 ML-ARC manual lockout automatic control relay as the last line of protection for a LiFePO4 battery from under-voltage. I need some type of battery voltage detection switching device that provides the input to the ML-ARC to de-energize the power circuit at a...

Anyone have a good experience buying 4/0 MTW or Marine wire. Any recommendations ?

I would like to use the Victron smart BP-65 to disconnect the solar panels from the solar controller at the battery high voltage set point as sensed by a BMV 721 smart battery management device. I hope to use the BMV 712 high voltage relay as the remote relay for the BP 65, with the BP 65 in...

Magnum MSH3012M inverter/charger/pass thru and Battleborn LIFEPO4 battery settings using the ME-ARC controller. Anyone have a resource re: Battleborn LIGFEPO4 battery settings for this inverter, or experience making the settings ?

Has anyone built a slide mounter solar panel setup, one panel directly above the other for travel, slide out deployed for camp (and shade) ?

Thanks for creating and backing this forum financially Will. It has great potential. I used to follow several forums of interest to me. Then many went to facebook for social and technical shared points. It's an awkward place to share group info. Forums work so much better. Hope to learn and...
