Anyone find or develop a (semi-)mobile solution for rack batteries, that is "affordable" (<= $125)? I'm struggling to find an affordable solution for storing my server rack batteries. I tried out a server rack in my budget, which advertised that it could handle the weight of my two Aolithium...

There more I assembly up my Aolithium test setup (before I send it to its off-grid location), the more I want disconnects or breakers in place so that I can rewire things without shutting down everything. Right now, I just have a disconnect between the battery and a bus bar. Everything else is...

I'm getting nervous about the exposed metal in my test setup. the most egregious things are the exposed 5/16" studs on my inverter. Most other things are covered ok. I can't seem to find any good off the shelf solutions for that. Are there covers that go over studs and maybe over the lugs a...

I have 2 Aolithium rack batteries, and got my Victron 150/35 connected in and doing some light solar charging, and noticed a couple of things, raising a couple of questions: Should I expect the batteries to eventually match charge levels? The master/top battery is charging faster than the...

I've already seen recommendations not to drill the terminal out to fit the bolt (on my disconnect and on t he bus bar). I'm not sure that I have the tools to cut this cable and put a new lug on it, and I don't have 3/8" lugs for 4 AWG cable, yet. Are there other coupling suggestions to get from...

I just got in a holder and class T fuse, separately ordered, and the Class T fuse doesn't lay flat on the holder. I haven't been able to figure out, yet, which one of these is "off", but, since it is the same in any orientation, roughly, then I'd say it is just one of them. What would you do? I...

A vendor recommended a 58V 40A fuse for the Victron SmartSolar 150/35 output, but I was reading the manual/specification today, which stated that the equalization voltage can get to 64.8V. I haven't gotten an answer out of Victron or my local vendor, yet. What fuse should I be using on the...

I am looking at some panels that, if I put them in series, the Voc would be above 150 V some very low probability, by 1.064 Vdc. I'd expect the voltage drop over 10-30 ft to make it even less of a chance. Does this seem like a reasonable chance to take?

I'm researching fuses, and seeing different recommendations, and having a hard time sorting it out. I the following lines I think I should fuse: Battery bus-->Inverter: 100 A, 48 Vdc Could be 200 A down the road as I have two 48 Vdc batteries in parallel Battery bus -->12 Vdc regulator, 40...

I'm getting 2 Aolithium rack batteries in, and want to get a rack to store them. I'd like possibly 2-3 extra U in order to mount other things inside, potentially. I search through for racks, and I noticed some people use the EG4 rack. Any other racks people recommend? I think I'd like to add...

I don't have enough panels to get the total solar panel output voltage great than the voltage my MPPT needs to charge at 48 V levels in my test setup. I thought I had ready once about something you could put in between your solar panel and the charge controller to boost the voltage, but can't...

What gear would you recommended for someone building a new off-grid setup? I see that ammeters are something that seems common, any specific ones that people would swear by? I have a multimeter with probes, but that's really the only electronics diagnostic tool I have.

I've got a 2-unit Aolithium rack battery set coming soon, and I'm reading up on charging. Right now, I have a Victron 150/35, and was planning on using solar to charge. I noticed that most people seem to have a dedicated charger for getting their batteries initially charged up. Is solar still a...

I am building an off-grid system off which I need to be able to run something as heavy duty as an electric demolition hammer (but probably not heavier). E.g., 1800 - 2200 W on 110-120 Vac. My system, so far, is a Victron 150/35 with two Aolithium 48 Vdc rack batteries in parallel. It doesn't...

I am building a 5 kWh system for a glamping context. I plan to get 3 kW basic inverter (also could use suggestions, will run some power tools) and have a Victron 150/35 charger at the moment. I am definitely buying off the shelf used or new. I've watched some videos, and specifically looked at...

My test setup is the following: Panel 1 x SanTan Solar 240 W panel: ~38 Voc, ~30 V for max current (Imax ~8 A) Controller Renogy Wanderer 10A (PWM) HQST 40A (MPPT) (in photos; not using the Wanderer anymore) Battery Weize 50 Ah LFP (12.8 Vdc nominal, 14.4 charge voltage) Cables 10 AWG...
