Just in from an early evening beer and bronzie, a stunning day. Powers out of it now here (sub 1,050W incoming) yet had a 41+kWh day off of the home systems. Nicely balances the waning output of Graig Fatha as the season changes.

Also had an 82 mile run today with SWMBO in the I5 to collect some furniture. Almost all miles are now back in the tank and purely from the Sun, epic. Really epic. :ugeek:

41 kWh :o , is that a PB ?

Nowty Towers has been struggling to keep up with visitors using more hot water and several return trips to London in the EV but still near 100% solar.

Today was a 60 kWh solar day and needed it to charge the EV back from London yesterday. Almost 20 kWh added to home battery and 33 kWh added to the EV today. :mrgreen:

And all WT1 going into the VB. :twisted:

Yep, a PB, peaked at 6.6kW incoming. :) . You're doing quite well too! :lol: I echo what you said last month, amazing how much power can be absorbed by the EV's. Even more amazing that we then waft about on sunshine. Away for a 100 mile run today, no grid touch required. Also :mrgreen:

Well Nowty, a new PB.
4.5kW from the solaredge and 3.19kW from the Victron. Round it up to 7.7kW. :D

These values were momentary peaks, more typical for sustained time periods are below.

3.19kW has never been seen on the Victron as it was finished at the closing of the season last year. I hope for one cold clear day before the weather heats up just to see what it can do. :twisted:

i'm at my parents house, my dad still lives here, 10Kw installed in 2011 with 3 inverters, I bought 8 410w panels last november and installed them on the spare bit of west roof, well 6 of 8, roof needs repaired.
I'm eyeing up the garage roof maybe another 9 455w panels and a load of storage 8-)

I have one further possibility of system extension in the realms of normal(ish). Wondering at a fifth string feeding into the Victron charge controller. Could place this string up on the top roof of the loft conversion where it would be fit and forget. Can connect it into the existing string of three on the roof already with branch connectors.

As this would be my most defo last set of panels(honest guv) I am wondering if there is much much room for movement in the panel voltage on a set of three? I'd like to stretch the panel size as much as possible in this last set.

Does anyone know if the voltage envelope can be pushed and by how much?
I am currently four strings of three,
325W
OC 40.87v
MP 33.97v


For example, can I slip this panel in as a string of three?
