Firstly - these data now come with a health warning - February has seen a few outages in the PowerVault data portal, and in exploring that, the tech guys have also noticed some inconsistencies in the data that has been logged to date, so I'm not 100% confident of the numbers in terms of kWh "saved" - they could be too high, or too low, so we'll just have to take it as it is for now.
Anyway - Feb
Generated 83.43kWh (2nd worst Feb since install!!)
Battery discharge - (warning!) - 53kWh
ImmerSUN diversion - 3kWh (in Feb 2016 this was 22kWh - so the greedy battery has stolen all of that!)
So, the Battery has probably saved at least £7 this month in imported electricity avoided, quite a gain over January (if true!).
Either way, gotta love batteries!

Would you happen to know his Import figure for Feb 2016? The comparison between 16`/17` may be of interest.
Imported 220kWh. Difficult to compare directly of course - but with less generation (Generated 119kWh in Feb 2016 vs 83kWh this Feb), we imported 10kWh less juice.

I'm interested in the idea of going off grid during the summer months (June, July, august) by adding a further 3 kw to our existing 4kw of solar and obviously a battery array. I just can't see how you calculate how big the batteries should be for the size of solar you have installed. I saw that Mart mentioned 5kw of storage for his 4kw array and wondered how he arrived at that figure?

The increase in new installations was mainly due to a 40% drop in prices over the past three years. German solar association Bundesverbands Solarwirtschaft expects their number will double to 100,000 in 2018.

Sunplug - get smarter with solar storage
Install the latest li-ion home battery for £3,999 (inc VAT) and start saving on your energy bills.
Haven't got time to digest it at the moment but seems to be promoting a new LG battery storage system.

The price appears to be for a 3.3Kwh battery (which can discharge at 2.5Kw) together with an inverter (does this make is less efficient than systems which link into the existing inverter Marty?). Unfortunately I cannot find anything else out about the battery itself - crucially expected cycles. Still it looks like a step in the right direction.
