Hi guys,

Whats the point in showing off daily outputs !?
You know that "our" weather is different from the front of the house to the one at the back of it !

Just post the link to your PV system,the public link and let people scan and view themselves.
Here is my ABB PV:

Happy harvesting..
Be good !

Well Solis does not seem to have option for public link or I cannot find it.

I knew that ABB is a premium product,industrial grade inverter but i dont think other inverters haven't provided a way to see the results without logging on to their systems...
So,to see your parameters,you need to login everytime !??

It is not inconvenient as you can save login or if using app it is just one tap to open it.

The link you provided also provides basics and not usage and other stats. Maybe other providers consider it a security issue.

The sun sets on the last day of the month so let the numbers begin.

North Wexford

6.2kw facing SE 152

Total generated 575kw

Today 31.2kw

Exported 104.7kw

Amazing month for us. We generated 230kW with a peak of 3.08kW today which is 99% of our system total. Best day was 21st at 13.5kW.

Our battery is fully charged by 2pm most days and we exported 30kW to the grid (no FiT) which isn’t too bad. We’ve only had it three months so we’re still learning how to make the most of it.

South Dublin, 5 panels SE and 5 panels SW at a 26 degree tilt, 3.1kWp.

You will be watching evey weather app like us.
Once everyone in the house gets it and uses it at the right time, you will reap the rewards.
Best of luck

SSW facing 4.3 kWp, Mayo/Roscommon border.

March yield - 336.4 kWh.

Daily average - 10.85 kWh.

Worst - 1.1 kWh on 7th.

Best - 24kWh on 29th.

Struggling to retrieve other figures out of crappy solax website.

wexfordman2 · 01-04-2020 12:06am

Well, my system is on now for exactly 1 year, and here is what it is reporting

A 5.85kwp system with a 5kwh battery and eddi diverter. I used the battery for night rate charging over the winter months, and now am back again to to purely solar pv charging.

So 12 month figures show

5.6Mwh produced
6.6Mwh consumed
2.2 Mwh imported
1.2Mwh exported

Battery throughout 4.1Mwh

Can you not get details off the inverter itself ?

wow, only 5kWh exported out of 403.8kWh. That's very effective.

7kWh battery, constant monitoring/projecting and trying to use as much as possible during sunny periods helps a lot.
Still thinking of bumping up the battery to 10kWh

193.4KWh / 31 days in march = 6.24 KWh per day, divided by 2.6KWh battery capacity = 2.4 full cycles per day.

How are you managing to do 2.4 full cycles per day on the battery?

No idea

IS that good or bad?

Depends - if you are managing that many cycles just from sunshine, it might mean that your charge/discharge rate (in amps) is relatively high, so the battery will wear out faster.
Perhaps you are doing an overnight cycle, charging from night rate, and discharging in the morning?
Perhaps you have an immersion diverter, that is sucking from the battery instead of just using excess juice from the panels?

I have no idea....sorry I think I have Mode 2 set on my system:

This mode designed to balance the use of PV during the day and battery to supplement when the PV is insufficient. The aim is to be grid neutral and priorities the home load from any source and uses the grid as a last resort.
This mode does not use supplemental AC charging overnight.

I have the same as inverter, mode 2 is when the battery charges by solar only and discharges on demand.

Yeah, but it's battery throughput which means charged and discharged, so a single 2.6 cycling once would be 5.2kwh throughput?

I know you have double the capacity, what mode do you put it in?

With system that size and a small battery it is possible to do multiple cycles. I checked my charge and it was 143.7kWh in March which makes 4.6kWh a day and that is 0.65 cycles on 7kWh battery. It would probably do full cycle if I did not turn on heavy users in the morning. On good day I have 50% charge at 9am.
I would say the battery is too small for this system it may not last with this usage.
