Woke up in a sweat last night because I had a dream that I spliced some wire and forgot to slide on the heat shrink first.

Built some fuse holders to go inside some Sunpower batteries I am rebuilding. The straight tab on the left and the s tab on the right have female threads built in - the nuts on the bottom just hold the insulator and hence the fuse is supported. So, creep of the fiber insulator will not cause...

Do they mars ground their systems with marsing rods?

So I'm soon to replace a single xw+ with dual pros. No external transfer switch. Because of the inverter internal relay (I'm off grid but have a generator for low battery (rare) and it does exercise monthly), the combined load during a switch cannot be above 60A. So, by having two pros instead...

I have an XW+ that I've been using off-grid for four years. Nothing wrong with it. I'm about to power the system down to swap to different batteries, and was perusing the operators' manual for refreshing my mind, and I saw this: AC_Coupling AC Coupling function is enabled by default (Advanced...

My current system has been working more or less flawlessly for four years. One Schneider xw+, 2x mppt 60150, 5.7kw panels, 14kw kohler genny that almost never is needed, scp, gateway, and 4x simpliphi 3.5s, voltage controlled for 56V bulk/absorb for 6min and 54V float. Also ags for the kohler...

Hi All, Helping a friend install panels to run into an eg4 6000. We have 16 420W commercial modules, and will do 4 strings of 4. 2 strings will combine on the roof, and each 8 module group will go into their own mppt on the eg4. The specs of the panels are as follows: vmp 72.9 imp 5.77 voc...

Just an fyi - I've been watering 17 fruit trees almost exclusively with greywater for four years. It's been long enough now that I feel confident in reporting that this is fine. We use oasis/biopak for handwashing dishes and laundry. Griffin remedy for shampoo (but other stuff gets mixed in...

I'm not quite sure how I managed this, but my insight facility will not allow me to change and settings on one of my xwpros. I had managed to update the firmware, and had been messing around trying to get a bms recognized. I can power on the unit in standby, but the fan kicks on every minute...

Hi all, A friend had some sunpower battery systems that he modified to basically keep the xwpros that are in there, and asked if I wanted to try to use the batteries. They are mostly in the 52V range sitting there. They have some sort of internal relay that activates when you push the power...

Off grid and thinking of the proper way to swap out some new batteries. Can you remove batteries while the xw is in standby, or should the xw be "off?" Thinking of this order of operations: Turn off loads breaker Disconnect pv from sccs Put sccs in standby (or can I do this with pv still...

So, I heat my stock tank with two parallel thermal panels. Manually plug in an ac pump to an extension cord each day. I bought a kit to control it automatically with a few T probes. It has a horrible manual, but should have the ability to heat an aux tank, so I can overheat it and then heat...

I had a previous and uneventful thread about trying to get some Sunpower 6.5 batteries working. I'm starting a new thread because I gave up on making them work, and am now in the process of stripping the existing bms and making the newer jk inverter bms work in these boxes. I have already done...

I see some mention of jumpers in the imo documentation, but it's not clear to me how these are supposed to be used. I also don't see any mention of the jumpers on retail sites. I'm looking to combine two 4s strings, twice, after the disconnect. Looking to use either two 4-pole imos or a single...

Does anyone know how the low T setting is supposed to function? I set mine to 2degC. I have 8 bms in parallel. If the shed gets near this temp, allowing for error in the bms sensors and transducers, I was wondering if some of them were to stop charging (but allow discharge?) that by the time...

So, I've been running 4x phi 3.5s for almost four years. Never thought I had any issues until recently. My generator almost never kicks on, and in fact my first two or three winters saw no generator activity other than exercise. 14kw Kohler would run for an hour and a half or a bit more...

I've crimped my share of lugs onto pretty fat wire, but not done any ferrules. Looking around at ferrulesdirect, I see mention of 'true awg' and 'awg.' what does this mean? Also, are there standard pin thicknesses for a given wire awg? I've removed some ferrules that were installed by others...

I get that the load is resistive, but the sound from the xw is quite pronounced, and I'm worried that it's causing excessive wear to the inverter. Should I not worry? It's an 1800W unit, and even pulses on heat-up, which I think is silly. It's stated it's for more even heat, which could have...

I inherited some surplus Carling DC 125A breakers that I'd like to use between my bms and inverter/charger. Some of the breakers came with some scrap/cut wire with lugs attached, which were attached to the breaker studs. The studs have two nuts and two washers each (plus one star washer...
