    Has anyone take the plunge into a PV fed home storage system. I saw Jim Ingram asked some time ago about home made systems, - probably smaller than I was thinking, but did you get anywhere Jim?

    I have my little off-grid system entirely separate from my grid-tie system, though it does have the effect of leaving more of the grid-tie energy for export or other appliances:

    A nominal 2kWh of usable storage, though with my ageing batteries probably 0.5kWh now!

    Hello Damon,
    It's nice to hear from you again, it's a long time since I saw your name on this forum, perhaps I'm just reading the wrong threads.
    For some time now I've been trying to forward plan the CH for my home once my current biomass boiler breathes it's last. It's got a while to go yet but with renovation work underway It makes sense to make provision for e.g. for electric UFH, even though this isn't going to be sufficient for the whole house. The other tack is to install ASHP either Air/Air or maybe Air/Water, TBD. In order to power all this, it kind of makes sense to utilise the 10kW of grid tied PV I currently have with some form of storage. I'm just putting a toe in the water so far and playing about with numbers. I'd had a look at a 6kW li ion system but cost and capacity wise I wondered if it was worth it, payback 'n all.
