This Dutch company make bespoke BMS systems for car builders. May be of help.http://www.wdrautomatisering.nl/

I'm using CATL 3.7v lithium Ion NMC cells and it seems the charge discharge curve is different. With NMC it should be possible to use V set points.

Hi, I'm on a similar journey, also being a great fan of Outback. I have at present a 24v system (1000ah) and have an VX3024 inverter and 3 Outback FM80 solar CC. So from the inverter plus the CC I have 4 relays, voltage controlled. Could you not use these CC relays for extra switching. I have...

I'm very sorry but I don't know what you mean about Nordic. I envy you your offgrid status. especially for so long. if only I could ever get there. Start with the 1st step. and then the 2nd etc, it's theonly way. My intention when I came in here was to offer assistance based on real life...

WT is on a 12 mtr hinged tower. I should point out that the over 40Kw day was a 50Mph day with 70MPH gusts. Wind today about 25MPH. Today solar PV has done around 6K and the wind had made 14Kw in 14 hrs. I'm not obsessed with the daily data as I have too many things to get on with. So no I don't...

Hi to you all. I'm new to this forum, since just a couple of weeks ago. But I have lived completely off grid for the last 25 years here in the UK. I started to read this thread as I have an interest in WT but I confess that i have not read all 83 pages so forgive me if i say something you...

The new battery that I'm boing to have to repurpose, as it is currently all wired in series to give 400VDC is from a Peugeot Boxer van 2022 plate with only 1000 recorded miles...

My panels are in 4 arrays and they are on different axes. One array is set to get early morning SSE so max power when the house is waking up. One array is set more to the west to get the evening rays best.

Well sorry I missed this, Power demand has grown here over the years along with greater generating ability. A 48 V system perhaps with 2 inverter chargers in parallel will enable me to have higher demand when needed. Eg if we have the washing machine on and then put on the coffee machine, on...

So I have done more research on these Peugeot battery modules. It wouls appeasr that each module has it's own slave BMS on board managing the 6s2p cells. Each module is connected in series (data on a daisy chain) linking back to the main BMS. The daisy chain consists of only 4 wires. So I...

Have I posted this in the wrong place? https://diysolarforum.com/threads/re-purpose-peugeot-e-208-battery.80269/

I stand (sit) corrected. Product is designed for domestic use, so 4 times an hour use is 15 minutes per sit down!!

As many as you like. Say 10 minutes per sitting, do the maths,

Hi, I run a small off grid glamping operation and have a Cinderella toilet LPG fired unit for visitors to use. The unit has been operating for 3 years faultlessly. The LPG fired incinerator requires a dc power supply for the ignition circuit, a small battery will do although i actually have...

Hi all and thank you for your welcome. As I mentioned I have recently obtained a near new EV battery. Done only 1000 miles on a 2022 build date, so perhaps been charged 6 times. The battery as built for Peugeot is as follows. 51 KWh. Pack voltage 400V Capacity 127.5Ah. Total cells 216...
