Yes John, It worked out well with the Solis RAI-3.0KW 48ES 5G AC Coupled Inverter under £680 delivered from TradeSparky https://www.tradesparky.com/solarsparky/battery-storage/solis/ac-charger/solis-rai-3kw-48es-5g-ac-coupled-inverter. Fogstar 5.12kWh rack batteries at £1350 delivered...

No, I have a 3kW MCS for my FiT system.

Its been a bit of a journey and a steep learning curve with help from members of this forum and others, but at last it looks like I can mostly leave my Solis ac coupled inverter and its gaggle of Fogstar batteries to just get on with it. Being a self installation I had to apply to my DNO for...

I read that John, thinking you had found the holy grail and the link to this marvel would appear in the text, then I got to the end, re read it and oh no you mean HA ;)

I have since 2014 been using an Eco-Eye https://www.eco-eye.com/solar-power-products monitor for easy display of pv and grid energy updating every few seconds on a IHD. There is a serial output to which I have an original Rasperry Pi with just power/ethernet/usb to serial lead & an SD card with...

More battery abuse, If I have 3 Fogstar batteries correctly addressed and connected via the RS485 links and I strap them all in parallel & place the Inverter cables to top left and bottom right as you should. Can I then if need be turn off the middle battery BMS and breaker plus flick the...

I think perhaps Fogstar might if asked make a video of a typical install for potential customers to give an idea. I don't yet have a cell balancing problem and I have really used and abused this battery. Happiness is 48-55.2V I am told ;) Ooops. The cells seem to balance themselves quite...

I couldn't get coms on USB longer than 1.5mtr in this instance :)

No, two batteries to add to the one I had already so 15kWh total, more than enough for my use but I should be able to do some export in summer and buy cheaper & store in winter. That's the plan anyway.

I just had some more batteries delivered today so more use for that extended lead ;)

I used the bms tool to select Pylontech in the battery BMS and chose Pylontech in the inverter battery choice settings. Its been running fine and I just took delivery of 2 more Fogstar batteries today.

OK its been very quiet in here ;) I have figured it out and I will put the parts required here so if others come across the same problem it may be of help to them too. The BMS RS232 socket is RG11/12 size and the cable is 6 wire to the Prolific PL2303GT USB to RS232 bridge controller. As I found...

Not quite solar pv but associated. I can with a laptop and the correct lead with is RS232 from an RJ11 port on the battery to a USB conversion male plug, log into pBMS tools and realtime read my Battery stats. My battery is in the garage and I want to read it from the comfort of my lounge, so I...

http://www.precisecalibration.co.uk/product/avo-flexiclamp-200-clamp-meter/ The Megger Flexiclamp does what you always thought clamp meters should do – measure current in multicore cables and power cords without the need to split them.

If moving the panels gets a large improvement in output than was historically on the FiT they will be asking questions I would have thought.

And yet Pylontech make a point that their 5000 series batteries can be used with a DOD of 95% and your 3000C has a DOD of 90%. So they must make this adjustable via the BMS? Did you get information on how when you purchased yours?

Sorry to hear that news.

I set mine at 15% and 5% as if we get a grey day and the battery stays at 15% for longer than 14hrs the battery cell volts drop to a level where the BMS will force a recharge from mains which you don't want. In my case that's 3.4kW for 20mins to top up the cells. So leaving it at 20% does 2...

In the Solis menu will be something like mine which is The OverDischg SOC can be set from 10% to 40%. This is the one that stops it at 20% in your case. The ForceCharge SOC can be set from 5% to OverDischg SOC. This is a failsafe backup to start an auto grid recharge if the battery goes below...

Going to play devils advocate here, since July 2022 Nigel52 how many power outages have you suffered in Poole and how long a duration? My Solis inverter has the capability of running on when the grid fails but I personally really don't consider the feature worthy of the extra work involved to...
