Just reading through this again and realised I hadn't attached the easysolar spec ! doh ! Was clearly already moving on and thinking about the PV inverter end of things. See easy solar link below. Wish they did an 8k version of the easy solar too, especially as there's 8, 10 and even 15VA...

:ROFLMAO:Looks promising, was wondering if the delivered manual mentioned it, I couldn't find any reference on their website. Will be interesting to see how things progress after a few weeks use, all the best.

Cool, exciting stuff Oldman22! Does the BMS on the Fogstar 15kWh rack actively balance the batteries / cells ?

Sounds like OP has 2x4 into MPPT#1 and 1x6 into MPPT#2 ? or should that be 4x2 into MPPT1? - is there a common convention for series and parallel combinations ? (4s)x2 ? Perhaps need a bit more info on the current system...

Hey, thanks Ronski Yes seems like a few victron ENAs are taking their time, sure they will get there thanks for schematic, will be interesting to see, don't feel you have to do it particularly neatly on my account, anything gratefully received :) Been exploring a set up of around 2x10 x...

Hi Ronski, posted a query about your Quattro based system in a new thread here https://electricianforum.co.uk/threads/quattro-install.56174/#post-541846 Locked to prevent being resurrected (again)

Hi Ronski was reading this thread... https://electricianforum.co.uk/threads/new-consumer-unit-required-does-it-mean-none-fire-rated-down-lighters-need-replacing.56129/page-2 and was interested in your system. Just curious, what kwp of panels do you have connected to the victron MPPT unit ...

w.r.t Fogstar ESR51.2V 5.12KWH Rack Battery 80% DoD on 5.12kWh is 4.096kWh usable very nice to see the fogstar is heated above 5degC the round-trip efficiency would be nice to know, assume 95% £1350 (+VAT??) Presume the BMS will be firmware/software upgradeable to account for new...

You're referring to a Sofar ME3000SP ? What additional functionality or performance are you hoping the sd card will provide?
