Hello, I have the setup and attached a screenshot of my Victron settings for your reference. Could you please check and let me know if they are appropriate for my current setup? In particular, I'm uncertain about the proper "Tail current" setting. Thank you! Marc SETUP: Victron Energy...

Hello. I hope everyone reading this is well. My 4 Battleborn 100Ah / 12V batteries, configured in 2S2P 24V, have been disconnected from my solar panels for about 6 months. As I prepare to reconnect them, I wonder what the proper protocol should be. Should I first drain them completely? Is...

Hi, I bought four 100 Amph Battle Born batteries six months ago. I use them in a 2S2P config, using them daily. I want to buy 2 or 4 additional of these batteries. Will the age difference be a problem, or can I add the new batteries to the existing ones to form a larger battery bank? Thanks in...

I've currently got four 100 Ah 12V Battle Born Batteries, connected 2S2P to form a 24V battery bank, for 4,800 Wh. I want to add capacity. Adding another 4 Battle Born would cost $3,500 and bring me up to 9,600 Wh. It would also be a hassle wiring them all together. I'm wondering if I should...

I've got the ExpertPower 12V 20A Smart Charger for Lithium LiFePO4 Deep Cycle Rechargeable Batteries. I've got four 100 Ah 12V Battle Born Batteries. I've used the expert power charger to charge up a single Battle Born before. Can I also use it to charge all four batteries at once (connected...

I'm flummoxed. I use six 350W 41V 10A panels connected in series with a 250V / 100A Victron charge controller connected to four Battleborn batteries in a 24V config. The Victron shows the solar voltage as 110V, whereas if measure the solar cables directly with a multimeter, it shows more than...

Hello, I'm trying to figure out how to best use ten 350W 41V 10A solar panels with two separate solar units. I currently use the 10 panels in a 5S2P config with a 250V / 100A Victron charge controller connected to four Battleborn batteries in a 24V config. I also have a separate Bluetti 500...

I'm thinking of adding to the currently 4 Battleborn 100Ah 12V batteries I have in my system whose specs are shown below (has ten 345W panels). How many more batteries should I reasonably get? Is there some kind of formula or logic for that? As a thought experiment, adding thousand batteries...

What kind of additional component(s) are required to turn the off grid solar system whose specs are below into a UPS-like system that powers connected AC devices via the batteries/solar but switches to powering the AC devices through the grid when the solar-powered batteries falls below a...

I have the two solar systems ("A" and "B") whose specs are shown below. I wonder what the smartest way might be to integrate the Bluetti EP unit from system B with system A (without using the Bluetti panels from System B because they are just "splash proof" but not totally rain proof so I only...

Hello, I have four Battleborn 100h 12v batteries that I plan to use in a 2S2P configuration. One of the batteries tops out approx. 0.2V below the other three. For example, after fully charging all four batteries a couple days ago (and not using them), three are now at 14Vand the one other is at...

I've got ten solar panels with the specs shown below and a 250V / 100A Victron charge controller. What's the best way to wire the panels? I was going to connect them all in series but I suppose that would exceed the 250V limit of the controller. Thank you for your help. Marc Charge...

Hi, I've just added two Battle Born 100 Amph lithium phosphate ion batteries (#3 and #4 as shown below) to my existing two (#1 and #2). Even after going through a cycle of fully charging the four with my solar panels, the old pair each are at 13.99V, but the two newbies don't go above 13.32...

I want to connect five Mission Solar Panel 345W panels (see specs below) to a Victron 250V 100A charge controller. I'm wondering: a) how to connect the panels, and b) what gauge cable I need to use to connect the panels to the charge controller. It seems that the Victron is powerful...

Hi, I'm looking to fill in the blanks for fuse ampacity and wire gauges in the schematic below (my first project, and I got all the hardware, except for I'm still feeling quite insecure about wires and fuses). I first posted this in other forums with my own best guesses, but I realize I should...

If appliances connected to my battery draw 200W continuously, and if my solar panels connected to the battery via the charge controller supply 700W, would that supply enough power indefinitely (hypothetically assuming there is 24-hr sunlight)? Thanks :-)

Hello there. Happy weekend. What size stud fuse block should I attach to the positive terminal of the left battery in the set-up shown in the schematic below? 300A? Thanks for you help.

Hi, I hope everyone reading this is well! I'm about to put together a 24V/4000W off-grid solar system. I got all the parts, but I'm feeling a bit nervous since I'm a newbie. So I drew the schematic below of what I'm planning to do with the hope that someone can help me catch anything wrong with...

Hi. For the 24W/2000W off-grid solar project at https://www.mobile-solarpower.com/2000-watt-24v-solar-system.html Will says to use 4 gauge copper wire to connect the components. I bought a higher-capacity inverter(4000W/8000W instead of the 2000W/4000W one that he uses). Should I upgrade the...

Hello there, newbie question here. I just got four 350W Bluetti SP350 panels (VMP 35V, IMP 10A). Can I hook these up in series to the 2000-watt-24v-solar-system configuration at https://www.mobile-solarpower.com/2000-watt-24v-solar-system.html ? My current understanding (still adolescent...
