Home setup - 16 305Ah cells 16s. Originally with Seplos 200a v3 bms worked fine (actually really well after playing around with settings) and can bus communication to 8kw sunsynk/deye inverter until I tried to upgrade firmware, without decent instructions managed to brick the bms, no pc...

Anyone know what has changed from 0.4 to 0.6? What happens if you flash V10 with V11?

This whole idea has now been abandoned as the technical, safety and legal problems are too difficult to overcome. But as a theoretical exercise I have had another thought. Large (100 amp) 3 phase full rectifier feeding DC from factory 1 to grid tie inverter feeding AC to factory 2. C.Ts for...

In answer to filterguy - batteries will run at aprox 400v. 2stroke forever - the problem with having a separate inverter for factory 2 is that factory one has 5 separate solar arrays on different rooves individual inverters for each one ranging from 50kW to 15kW and all running at different...

Hi FilterGuy, Answers to questions: 1. Panel to panel is in the order of 50m 2. Factory 1 does not have any batteries but will have 100kWh by the end of the year. 3. Both are 3 phase 440v 4. System design would be for maximum 50kW transfer The voltage drop, either DC or AC would not be a...

AntronX - I am not keen to go down the route of extra complication of controlling several change over contactors etc. FilterGuy - I was thinking of HV hybrid inverter our end running at about 500v and 100a DC max. Problems I can think might crop up: How to get hybrid inverter to output without a...

Our factory have a large solar array and for 8 months of the year export a significant proportion of the generated power back to the grid without being paid anything for it. The factory next door use a large amount of power which is all supplied from the grid. We would like to export our surplus...
