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...
