Daily pv production

17.4kWh from 6.84kW array, SSW

If the weather is onside, it's getting close to nett neutral production

How do you get 8+kW, is your inverter not capped at 6kW?

How many kWp have you please?

Thanks,

I've about 9kWp but my app only shows it being clipped at about the 6kWp.

I'd like to know how close to the 9 I achieve.

Also, are inverters noted rated to oversize by 50%, is 9.9kwpnit a bit much?

Sorry folks if a silly question. If unit rate of electricity is currently approx 0.43 what is this sold back to the grid for?

First time poster in this section :)

12-FEB-2024 --> 14.5 kW/h of solar indicated (12.3kW/h real)

February to date --> 91.7kw/h of solar indicated ( 77 kW/h real)

I've a Victron system installed configured in ESS mode.

6.45kw PV panels temporarily ground mounted - PV's are moved and tilted to suit seasons.

2x 3kva Mutiplus-II Victron charger/inverters - configured in parallel.

2x Victron Charge controllers. MTTP 150 | 60 MC4

2x Dyness 3.6kW/h batteries (set to min charge of ~ 75% for winter as I'm paranoid :) )

Grid meter on consumer panel is a Gavazzi ET112 with wireless zigbee connection back to the Victron Cerbo GX in garage where gear is located.

This install was kind of accidental -- bought 6 panels and on inverter there over 16 months ago to run the garage / house pump / fencing etc as a project.. nothing too serious.. got it working ok but then the kw/h rates went up and the bills went mental! So bought more gear and re-programmed the system to run in ESS mode connected to house. Got all the DC wiring setup properly / conduit runs / cut offs / fuses etc (Victron Disty). Got the AC side signed off and NC6 cert so all above board.

This system was brilliant last year when I was on the Energia 44c per kW/h rate.

The indicated solar generation in a bit optimistic.... I've been doing loads of expts on this and as far as I can tell there is an error in firmware when running inverters in dual mode. There will be new firmware out shortly so will re try this. Also I might rewire the inverters with shorter DC Cables back to the distribution block. (Victron Lynx Distributor) . I also have a 1000a smart-shunt that I can put in serial with the DC side of the setup with a "VE.Direct" connection back to the Cerbo GX --> might try that too to see if that is more accurate.. The indicated "From Grid" value agrees with the house meter so that is accurate. Good!

Anyway the system works and keeps the bills down; and it's fun to play with the firmware and settings etc...

Take care T

FEB--2024

22.7 kwh today in East Cork. The new array did 15 of that.

I reckon on a proper sunny day the combined arrays should be capable of about 30 kwh in February.

Ya, I saw 8.3 kw peak power at one stage😁. Looking forward to summer. My graph looks similar to yours too, up and down.

4.3kwh on a 4kwp system today in south Dublin city.

26.6kWh on a 11kW e/w array. Mayo

looks like probably 6-6.5 kwh today, it's not massive, lots of cloud cover but have seen a huge jump in peak power in the past 2 weeks.

3kwp sw and seeing 2.4kw peak, and still doing 2 kw now the 1kwp ne is still mostly asleep for now.

Need to get going on these other 1kwp panels.

edit - 7kwh. a good run this afternoon.
