Can't remember all the specs, but not all USB power outlets are equal. Depending on what device you are planning to charge/run using one, the difference could be very important.

38.8 v output. Is generically used to charge 24v battery systems. greater than DCC50S max solar panel voltage spec....cannot use this panel with the DCC50S device.
Opinions are like, ....., well you know. Every statement about grounding should be proceeded or followed by a code, standard or listing requirement. There are no opinions that are valid. Just compliance. Codes. Standards and listings have been developed over time to address safety. Safety is...
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...
Don't entriely understand the comment.
But 'float charging'
has nothing to do with 'battery will not going to protection' as I understand systems.
Float charging will be controlled by the SCC float charge voltage setting. If that float charge is set to a low voltage say for 99-90% SOC voltage...
Yes, LiFePO4 batteries charge at max charger output amps until they reach about 14.6 v if the charger is unregulated. A charger will remain in boost state until the battery is charged to 100% SOC, no absorb charge. then the charger can be turned off or set for 13.6v or less as a max maintenance...
That Projecta DC/DC Solar charger looks good. Will handle AGM batteries at 14.4 v boost charge. A little low for LiFePO4 (needs 14.6v max) but would get them charged near 100%. Good price, available on ebay shipped from australia. Not sure of customs charge, if any.
I see that you use a battery chemistry LiFePO4 with Magnesium added to the Cathode. "EPS uses batteries made by GBS. GBS, like LiFeBlue and Relion, use Lithium Iron Phosphate (LFP) chemistry. However, GBS has an added Manganese to the cathode material and are referred to as LFMP cells."
If the battery cells are at 32 deg F, you should not charge them. They can be held above the ambient temp of the air in the vicinity by adding heat to the batteries as noted. The ambient temp in the area might be -20, but the cells can be held above freezing with heated plates inserted between...
Here's the Code and explanation (2011 NEC, I'll check if the code text has changed for 2020 code; 2020 code is 690.43 C) with minor language change. )
Article 690.43 F) (of course this is for photo voltaic cells mounted on Buildings with output voltage > 50V, but I think its a good guideline to...
Ordered one thru amazon, they shipped a BT-1, the previous model that's been out a while that works with the dc-dc chargers, but not Renogy DCC50S. What a disappointment in Amazon/Renogy warehouse.
Am requesting a Return for Refund. Ordered a BT-2 from Ebay today. Turns out same price, promised...
I have decided to go with a Victron MPPT solar controller (one selected to match my solar panel output power and voltage) and a Sterling DC-DC battery charger (Sterling Pro Battery Ultra BB1260).
You left out 250.166 C, D and E exceptions. (A grounding electrode is not always a 'grounding rod'). C,D&E allow smaller gauge wire for grounding electrode conductors in certain cases.
Here are a few of the grounding wiring diagrams for Magnum Power equipment. This first one is for a PT-100 SCC device. Not the PT-100 includes a internal GFDI2 device (Ground Fault Detection Interuption device). This drastically changes the system grounding wire diagram...
LiFePO4 batteries are either Automotive grade or Failed grade. EVE has branded their failed Cells with a B. No other manufacturer has done this to date. I think its a good thing they did the B branding. Just means it is a failed EVE LiFePO4 automotive cell, however. Generally they are sold at...
Does the DC Home app allow selection of LiFePO4 battery setting or USER battery settings ?
I got the app to run, blue tooth sync (after reboot of the DCC50S), and I see that it is set on USER battery setting, with the parameters I previously put in using the BT2 and Renogy BT app. Have not been...

Another day with sunshine. The BT-2 connected the DCC50S with the iPhone, no problems. There is about a 1 amp parasitic load on the 12v dc system in the camper, heater/ac thermostat, three way fridge eyebrow controller, smoke detector, propane detector. So if I turn the inverter off when not in...
NO, I mean you need to use a BT-2 to change the battery charge settings if you want to leave the DCC50S hooked up to the solar panel and battery continuously.
The reason is that the DCC50S default 'Li' setting is 14.4 v for Absorb & Float. I discovered this by testing the battery under solar...
The MHS3012M inverter and ME-ARC50 control are operating as stated in their user manuals. I don't leave the inverter energized with DC unless I am going to need 120v ac from it. As was pointed out above, it has a burden ampacity of 2 A DC, under no load. That's 2 AH for every hour it is...

I'm sorry boondocks, I thought I shared this with you:
The goal is to change the 'Device Status' on the Renogy BT app info page from Device Disconnected to Device Connecting.
May I suggest:
Unplug the BT-2 from the DCC50S.
Open the solar panel + circuit to the DCC50S (hopefully you installed a...
