In one of my threads a couple of months ago, I ask about adding batteries to this system and making it work with my Solar PV. The conclusion so far is that this is high maintenance and expensive, and not worth it for a system that will only be used once or twice a year.

The threadstarter Dave  has 6.5 kW  of PV  that  can deliver about 6-10 kWh   per day average in the dark months   and much more in summer

A say  15-20 kWh (brutto)  Battery  paired with a 3-5 kW offgrid inverter    can surely work all year round with the PV and as well during a powercut  , this could  possibly manage to  avoid an additional of 1500-2000 kWh   per year imported  from the Grid

That seems very high. December I would expect an average of half the lower of that range at most. Huh

It's about right. For my location (cloudy midlands) and 45 degree collector inclination, PVGIS classic gives daily averages of 9.5kWhr for November, 5.9 kWhr for December, 7.6kWhr for January and 11.8kWhr for February.

It still doesn't make such a system practicable though. 6 kWhr per day is much lower than most households' consumption and it doesn't take into account the occasions when you get a week or two of less than 3kWhr a day. E.g. 26 November to 1st December would have averaged 2.3kWhr a day with a 6.5kW system.

For more power, I could get a 2nd EU20i and parallel it up which would then let me run anything.



I didn't realize you could easily parallel them Al



Well I never, four of them  Shocked

"It still doesn't make such a system practicable though"  , oK !  then  please tell me  how practical a 6000  GBP   back-up Diesel Generator is !!!!!! , for the occasional   few hours powercut  !   .... While the system i suggest can utilize   nearly all power from the 6.5  kW PV all year round  bike

It's completely practical. It will enable the OP to have sufficient power available at all times, which is what the OP seems to want and no sensibly sized PV / battery system will provide.

It doesn't make economic sense, but neither does the PV/battery system.

... surely  it  makes economical sense to get free and even paid FiT units from the sun

Temporary back up power supply seems to come up quite often with the usual "buy a small genny and extension lead" followed by "get some batteries for your solar system". Just thought I throw this in the mix as a possible future option. Doesn't get over the issue of being away from home when the power goes out just long enough to defrost your freezer but covers other bases.

Have been giving this some serious thought obviously having a "free" supply of wood pellets makes the figures even better.

Looks interesting, do you have any prices and for which option?

Cheapest option is 6500 euro and most expensive incl additional battery 8500 euro. Obviously with euro dropping its looking quite cheap. There supposed to be exhibiting at eco build in London in early March if anyone is attending I would like to check out myself but might not be able to make it.
