That’s great
I my self have multi 2 5k that I got export approval for 5k last year but I can only generate 3k of solar although I have 4.5 k of solar I suspect some of the panels have failed. I do have aG59 relay in place but that was for the old outback system so that will help
Any way reading this blog its rather disturbing that Victron are not pushing for G100/2 compliance I understand why If not selling for grid connection ESS.
I just put another package together same as mine and checked the ENA web site and others G100/2 compliant inverters as I could have used my DNO G99/100 forms but now have to rethink which is a shame as my system is great and with node red installed makes for super configurable system I will have to go with an other manufacturer now so I guess uk sales will be down.

Panel rating is in lab conditions, getting up to a third less in the real world is not uncommon.
The offgrid pro device is now available to buy:
but it is £1200, which seems an awful lot for a small arm board and 2 relays, even allowing for the development and certification effort. I guess they aren’t planning to sell very many.
It’s frustrating that it costs about the same again as the inverter+cerbo that is actually doing all the monitoring and control, and are perfectly capable of performing this function themselves, for want of a bit of firmware work.
But right now this is the only way to fully comply so I guess they can charge what they like, and Victron will continue not to sell many ESS systems in the UK, even though people are crying out for the sort of flexibility they provide:
In this vid Gary is explaining why he had to get rid of his Givenergy system because it didn’t provide the flexibility (or power) he wanted. He switched to Sigenergy, but a lot of the comments pointed out that Victron can do everything he wants too. But of course it’s hard to recommend to people because they can’t legally connect to the grid without spending an extra £1200 on this box.
