Generator or Inverter for residential use?

[Sinbad]

The only time mine drops to less than 300w is if it’s rainy or really dark clouds. For light clouds it’s still decent production

What type of panels do you have?
Mine were JASolar poly

6x 420w Canadians poly facing north
8x 390w JA mono facing west
4x 365w Canadians east facing on 1200w micro inverter.

i guess it also depends on the inverter mppt. I know a few people that are getting more power with the sunsynk compared to axperts and 1 that’s getting more than with victron. I don’t want to cause WW3... just what people tell me.

With me, I get around 90% of the rated power at peak

 

[Sinbad]

I think the mono panels are better in less than optimal conditions

All connected in series?

Wow, that's 7.106 kWp, quite a lot for that 5.5K Sunsynk!
I have 6.120 kWp JA Solar monos, purely because of overcast conditions (I usually get about 1000-1100 watts, enough to charge my batteries and service my base load (around 450W) every day, regardless of the weather).

All facing different directions tho.

Yes. Well not all 18 panel, basically each line I described are in series. First 2 using invert mppt 1 & 2, and the 3rd on a micro inverter.

Well, the microinverter doesn’t really count so I think one could have the 6.5kw on the inverter and another 2.x kw on microinverter input.

It's still quite a lot, granted as @wingnut771 pointed out your panels are not all North facing, so the outputs are staggered. And as long as you are not overloading the MPPTs, which I strongly doubt.

To be fair, the Victron guy did mention he has one mppt and the panels face NE and NW

I think it’s to do with the higher voltage ranges of the sunsynk mppt compared to the blue.

It’s really overcast in fourways this morning. Not a bit of sun. Still managing around 1.4kw total.

The JA monos seem to be a lot better than the Canadian poly. Getting 53% more power on the mppt2 JA string compared to the Canadian string mppt1. Mppt2 is only 23% bigger than mppt1.

Good to hear.

I've just ordered 21 x 455W JA Solar for my next install.
The MBB (Multi Bus Bar) 72 Half cell PERC.

Planning on 3 strings of 7 each.

41.82v @ 10.88A x 7 = 9.5KW odd

Overcast in Kyalami / Midrand as well, was getting peaks of 2.168 kw at 09H32, and now 4.618 kw at 10H16 with my 12x 380W and 4x 390W JA Solar Mono Percs.

Edit: Yikes, had a peak of around 5.414 kw for about 15m at about 10H17, not bad for overcast and rainy weather (had a few drops of rain as well).

Gonna be strong, 9.555kWp
Which inverter / MPPT?

The Sunsynk 8.8kw

 

[RonSwanson]

The Sunsynk 8.8kw

So two of the strings will need to be in parallel then, to avoid the maximum Voc of 450V.

Yeah that's what I meant, I also should have said to exclude the 4 microinverter panels making AC.

 

[AchmatK]

Noticed some degradation in pv output over the last few days and then checked the inverter and I was only getting 17A on MPPT 2 and peak was at 7kw having normally been getting 7.6kw on a sunny day. Initially just put it off to days getting shorter.

Last time I hosed the panels down was about a month ago and we have not had any significant rain. Cleaned off all the dust build up and amps are back up to 18.5A and peaking at 8kw.

Guess I'll have to put in a reminder to clean off the dust every couple of weeks in summer.

Branch now in Midrand it seems. Great as no shipping costs if you collect, I would assume.
