Hi,
I'm afraid this is a somewhat general query, rather that a specific technical question. I'm looking for a home battery solution for a grid-connected home with solar panels and EV, with the following objectives:
1) To time-shift cheap energy provided by Octopus Intelligent.
2) To store excess solar energy.
3) To provide backup in the event of a power cut.
Now, there are some obvious candidates (Tesla/Givenergy/etc) with this specific use case in mind. But I was considering Victron as an alternative because I have Victron kit in my camper van and know it's excellent quality hardware and (correct me if I'm wrong) I think it's less reliant in terms of day-to-day operation on some back-end cloud system, but also the price per kWh could be quite reasonable with a stack of third party batteries.
However, after reading around a bit about Victron ESS setups, I get the impression that the scenario I'm describing, whilst certainly possible, isn't exactly the natural environment that Victron solutions are designed for, which seem maybe more industrial, off-grid and marine. Is this fair to say? Would I have to work harder at the configuration and software side of things to achieve what I want?
At a minimum, I'd need a system where I have a time-based SOC target, e.g 100% overnight which would force it into charge-only mode and a target of 10% during the day where it would happily discharge down to 10%. Ideally, I'd also have some other logic which would put it into charge-only mode during cheap slots during the day, which could be home assistant based or similar.
I think this is an extremely common use case in the growing home battery market, and I'd really appreciate any pointers to my questions.
