victron MPPT are sealed units, Victron has replaced it under warranty. But they don’t want the unit with this fault back. I’m asking because I difure I’ll resell it (with flaws fully disclosed). first I wanted to confirm it’s not a safety issue or would otherwise be unethical to resell the...

I think you misunderstood. The MPPT definitely has an issue where battery voltage is leaking back to PV inputs of MPPT. Most likely this is due to a broken reverse diode in the MPPT that usually prevents this. This MPPT shows 52V on PV inout at night, which is battery voltage. Anothe MPPT on...

I have a Victron 150/## MPPT that shows battery voltage level (eg 52V) as PV voltage at night when it should show near zero Upon researching it appears the most likely reason is a broken reverse diode. Victron staff commenting on identical issue: “the charger should switch to off mode during...

I got some LF280K a month or so ago. the barcode label specifically says “LF280K” on it see photo in my post here https://diysolarforum.com/threads/shenzhen-basen-review.25635/#post-302930

Picked up a pallet (20 panels) of these used panels Signature Solar just got in. https://shop.signaturesolar.us/products/208w-60cell-silver-poly-solar-panels-by-powerlight I tested two of the panels at random got 175w and 180w, which was A-ok by me. test context: - used a “WS400A” auto mppt...

Yeah, my issue is Seting 16 is set to OSO and it still charges from utility at night if setting 12 voltage is reached. Where it should just pass thru utility power when setting 12 voltage is reached, and keep passing thru without utility charging until solar becomes available to charge battery...

I appreciate the input. The nominal voltage of lifepo4 12v pack is actually 12.8v right? I have #12 setting = 12V because that is ~10% capacity left. When it gets that low I WANT the loads to be powered by grid/utility. But I DO NOT want grid/utility to be used to charge the batteries, only...

I want to add some panels and trying to determine if I can add some different panels and they’ll still play nice if combined (paralleled) with existing setup. Current strings are VOC 112.8, max power current is 8.27 amps. New strings would be VOC 137.6, max power current 7.24 amps. 4 of the...

Anecdote: ordered a set of 8 from Amy on 5/30 and UPS just got their hands on them. they’ll deliver 8/3-8/4. So just over 2 months. 3 months is definitely the right expectation right now though, between 2-3 months is now the norm.

Sounds like rhe LVX’s “OSO” setting does what I want. Unfortunately when my $350 1012LV is set to OSO it still charges off utility (AC in) if there’s no solar and battery reaches low voltage. So it goes into a bunch of mini cycles at night. Hits low voltage and powers loads from grid pass thru...

So what’s the bolt torque setting people are using on Amy’s Eve cells with the laser welded studs?

Thanks for the data sheet. Ive only taken it down to 10% (~12V) but max cell voltage delta has been about the same. It’s at 12.4V right now with a max delta of 4mv. During actual use (typically 0.1C / 30 amp 12V load), as I’ve watched it over the past week, max delta has generally been between...

Here’s an example barcode. I tried searching but it looks like we don’t know how to decode the three character date code? Last 3 digits of serial redacted to satisfy my paranoia quota.

Yeah I know I got lucky. I ordered when seeing some good reviews and getting into solar backup build research after Texas February snowmaggedon. Then noticed a lot of bad reviews later when doing more research… I’m not trying to steer people to Basen. I ordered 16 cells from Amy (Luyuan) myself...

Summary: Lucked out on Quality. Slow to ship due to stock issues. Experience: - ordered April 4: $484 out the door for (4) Eve 280ah - they contacted me April 15 asking to change cells to CATL 271ah - I missed that communication and never responded to them until weeks later after seeing they...

2nd option would work, $150. First option requires the 48V system and wouldn’t make sense as I’d just plug it into the 48V Victron inverter which I confirmed has settings that can do what I want (senseless to have all the losses at multiple voltage conversion points). But for me I’ll just...

AC to DC variable power supply is a creative idea, I like your style. However I don’t think it will work for my situation: - my load is 450 watts so I’d need a power supply that can do 12V over 30 amps. Is there one that won’t end up more expensive than the whole $350 MPP 1012 itself? - The...

SOLD — ALL ITEMS

Is there a way to get MPP Solar (1012LV) to never charge from utility, but leave utility connected to it for bypass purposes? My scenario: - powering computer that needs to run 24x7 - I want MPP to power it with battery until X voltage, then switch to utility (setting 12) - utility should only...

I got mine and trying to figure out how the AC terminals work. They look different than any of the data sheet photos and manuals and I can’t figure out how you screw open/closed the terminals?

Yes, 4S BMS and 4S active balancer still available. However I’m changing the price back to $70 for BMS. Heltec 4S Balancer will be $20 if purchased with the 4S BMS, but $25 If purchased separately (due to shipping cost). Reason is I’m starting to think about keeping it as a backup… I have a...

Good thread topic, I got 16 of these cells on order. I wonder why they added the additional base piece and couldn’t just find a way to add a permanent stud without changing the base contact area.

8S BMS and shunt are sold. 4s BMS and active balancer still available.

What I’m hoping: This is an off grid system and I can risk the panels/property by skipping grounding, while life safety is covered by PV combiner box w/ breakers on each string of panels. School me if I’m wrong, I’ve done my research but this is my first system. What I’m not worried about...

Prices lowered (shipping included) 1) Cheaper than ordering from aliexpress yourself 2) you still get a brand new unopened item. 3) you get it faster (I’ll mail via usps/fedex/ups within 1-2 days of payment) 24V BMS - $120 12V BMS - $60 Juntek Shunt - $35 Heltec Balancer - $20 Please do not...

So I've tried to reach Santan Solar the following ways: 1) Called multiple times over the past 3 weeks -- always got voicemail. 2) Left a voicemail twice. Nobody has ever called me back. 3) E-mailed both their sales address and a named person. Nobody ever e-mailed me back. 4) Filled out the form...

Derpsy changed his mind, all items still available.

Everybody having a good experience with this new model? I just ordered one. It’s existence made me change my plans for a 24v system up to 48v…. Can’t beat that 13 watt idle / no load power.

Thanks for confirming these are holding up with larger/heavier panels. Looks like a good simple option. How long have they been installed? Only thing that makes me nervous is a lot of similar products (eg renogys Z brackets) say something like “only for use with 100 watt and smaller panels” so...

Sorry if I’m thick, but to use right angle aluminum you’d have to drill extra holes through the side of the panel frame, perpendicular to the panel face right? Otherwise with the factory holes in the frame the holes will be parallel with the mounting surface. am I missing something?

Cool, PM’d you with details. 4S 12V BMS and 4S Active Balancer are still available as of now.

I’ve struggled on this simple topic after several hours of research… All the Z brackets I’m finding seem to be for 100w or smaller panels. Panels: Twelve 250w, 5.5 x 3.5 ft, 42 lb solar panels (santan solar used panels) Structure: existing wood patio cover (~8x8 structural beams and ~2x2...

Overkill is a small business that has been overwhelmed since Wills YouTube featured them a couple months ago. I have still purchased a 48v BMS from them in the past week, because 1) I couldn’t even be confident I was finding the equivalent .on aliexpress the way the stores/product listings are...

4 items that I ordered from China before changing my mind and deciding to go with a 48V system. All of these items are brand new, ordered via Aliexpress at the links listed. I haven't even opened the packages, I'll just be putting now shipping labels on and sending them to you. I am listing...

Is there any way to get Victron gear below their minimum advertised price (MAP)? The lowest price you’ll find online is the same everywhere online due to MAP. I’ve been able to find where I can buy it at MAP out the door (ie free shipping, no sales tax) but no lower. I’m looking to pick up: -...
