Is that a good idea or bad idea

Good idea, if your solar power is very slow (too few panels / battery too big). As you get more used to your system, you will be able to judge whether this kind of intervention is necessary or not.

Yay..... i'm learning
Thank you Mr Swanson

It seems that there is not much info on it. Best way is to find out, set it to 0W. Worst case is that it will think that you are tampering with it, and shut off the grid, so be prepared for a call to your muni.

You may also notice a small "bleed" back to the grid, particularly when a large appliance switches off. This is normal, the CT coil picks it up and the inverter quenches it. It is quick, but not that quick.

Have you gotten near to the 10Kw capacity before?

The 69w from grid, is that the trickle you set?

Nope. Only have 12 x 460W panels, so no can do. And i don't have enough appliances to pull such a load.

Trickle is set to 20. Dunno what that 69w from grid is ?

Schit. I hope you don't get an itch somewhere.

This is what priority load do:

My understanding is that priority load will prioritise load over charging the battery. Is that correct? So this is the setup currently. We want to achieve the following:

Battery must be fully charged and stay fully charged until 23:00, using primarily PV, only grid when necessary (at night)

From 23:00 to 8:30 battery must discharge to a minimum of 30%,using grid to top up to 30% if necessary.

From 8:30 battery must be fully charged and stay fully charged until 23:00 again. This to allow the battery to charge mainly through PV with as little grid power usage as possible and cycling the battery properly everyday.

During the day once the battery is charged, non essential loads can be powered as needed. Extra energy to be exported to the grid.

So, are we achieving that with this setup?

Sent a video to the husband earlier of our meter running backwards and it felt pretty good. IMG_20230126_110301.jpgIMG_20230126_110245.jpgIMG_20230126_110233.jpg

Thanks so much!

Out of interest, I'm not on pre-paid. I have a smart meter though, do you know if I need to keep the trickle in place?

I could be wrong on this, but I think the trickle feeding in also helps with quick changes in load.
The general feedback from most installers is to just keep it and pay the +-1kwh per day it uses.
So yes, keep the trickle in place.
 
Would appreciate some advice from our experts. Looking at adding a few panels to my current 5kw Sunsynk and AM2 Hubble. Supplier is quoting on JA Solar JAM72S30-550/MR panels as he has stock available.

I've read about the startup voltage of 150 of this inverter. When judging what the minimal amout of panels is to reach that, do one look at the "Open circuit voltage" spec or the "Maximum power voltage" spec to judge how many panels would reasonably work?

Budget is tight, but I don't want to install to few panels and then the panels struggle to produce anyway.

PS: Roof space is limited and orientation not ideal (West, Northwest). No North facing available.

Yes, Priority load means PV goes to load first then to battery.
It should be at 100% at 23:00 using grid if there wasn't enough solar.
It won't use grid to top up to 30% between 23:00 and 05:00 because grid charge is not selected.
From 08:30 to 13:00 you are forcing it to use grid for loads if you don't have enough solar, and only excess solar will be used to charge the batteries. This will probably cost you some unnecessary bought electricity but you will need to monitor based on your usage.

To be safe use the lower value which is Max power voltage at 41.96V. Either way you would need at least 4 panels to get started.

It's 125V for startup, 150V plus to start optimal production. I would go with what @furpile suggested, for minimum in series, use Vmp (under load), so 4 panels (4x41.96 = 167.8V).
To calculate maximum on an MPPT (500V), rather use VoC (because you will reach it under no-load conditions) so 9 panels (9x49.9=449.1V), which gives at least some room for temperatures under 25 degrees, and irradiance of over 1000W/m2.

The only problem is Isc which is 13.11, so expect clipping. It may be better to consider the 530 or 535W in the same series, it will then deliver full power of the panel.
