Solar panels installed 2010 - whether to switch from E.ON to Octopus for Feed in Tariff etc payments
Solar panels installed 2010, so currently receiving 68.3p per kWh FIT plus 50% x 4.25p export from E.ON. Octopus seems to be offering 15p for the actual export on its Outgoing tariff, plus the same FIT of 68.3p of course. Any experiences of the Octopus tariff? Looks to be beneficial at around seven times the E.ON rate…

Currently, my inclination is towards a 7kWh optimized system.…

Solax battery firmware
Last week I noticed that my battery was only charging to 80%. I wondered whether the BMS had implemented this as we'd been on holiday for a couple of weeks so the battery wasn't discharging and spending a lot of time near full. So I spent a week hoping it would revert back to normal. But it didn't. Today I phoned the Solax…

Hi, just a quick query, I take meter reading at the end of each month (sad ... I know but I like to know whats going on) and the generation for August = 212kWh, this is less than half what I have normally generated in August since 2012. I know weather wise August was pretty poor. My generation for the last six months,…

How do I automatically switch DHW Gas to Electric as tariffs change?
I have a 250L pressurised DHW cylinder. At present it is heated by a loop from the gas boiler which is controlled very accuratly by a Heat Genius controller. When on cycle it stays within 0.5C of target so all is well. It costs about £1 a day in the summer for the boiler to keep the DHW at temp. What I want to do is take…

G99 knocked back by DNO - trying understand proposed "reinforcemen"
So our DNO has knocked back the G99 application. Our supply is from 11kV overhead, with a 64A (16kVA) transformer serving just our property. The application was for 5kW inverter and AC coupled battery also with 5kW inverter. They've assessed on the basis of the battery not exporting but for some reason they still take…

Batteries and saving sessions
I am just wondering, in term of impact on one’s electricity bill, whether battery ownership is impacting on making money from saving sessions? Psychologically is it a challenge for those who take pride in achieving the absolutely lowest grid import possible to game the system by increasing consumption during the qualifying…

Best PV panel cables and connectors to use for replacing existing?
Possibly a long shot, but there may be a PV fellow on here? (I asked on a dedicated electrician's forum with a PV section - no reply...)I've had zero Riso for a while, so I'm going to replace all the external connectors on our ~12-year old panels. Fortunately they are on a garage roof with a high bank beside it, so access…

Chosing a PV inverter size.
Hi.I understand that inverters are, counter-intuitively, chosen to be pushed to their limits in order to maximise operational efficiency, and my 3.2kW system is, for this reason, handled by a 3kW Aurora. But just how much loss would there be to go the next size up, tho' - is there an actual %-age figure to suggest the loss…
