Generator or Inverter for residential use?

Final quote

Couldn't get the 400w panels but the 28 x 305w panels will work. First 20 panels were demo stock on display in the shop so got them at a discount.

5 year warrantee on the inverter. This is from a different supplier to the initial quote I received.

Delivery expected next week. Will probably only be able to start installation in a few months time. View attachment 868437

No batteries? Or am I missing them?

No batteries for now. Need to save up again for batteries which I'll probably only be able to afford next year.

can that system operate without batteries or are you just going to leave it uninstalled for now? if it were me i would rather get batteries now and panels later than the reverse

It can operate without batteries.

Current conditions has allowed both my wife and I to work from home so we'll be continuing to do after things return to normal. Our peak usage is during the day and not too concerned about load shedding right now.

It can take generator input so if push comes to shove I'll get a generator for backup. The plan is to add 24kwh of battery backup and eventually disconnect from the grid. Our laptops and routers are already on backup systems.

Name of supplier? Never heard of Sunsynk before, but it looks good. Need to do more research.
 
What is the max voltage of the MPPTs? 350 sounds high.

LRG Solar

There are few places that sells the sunsynk inverters.

Ellies quoted me R39k including Vat.

Invest solar quoted R31 280 including vat and delivery

Another reseller in joburg quoted R34k including vat but excluding delivery. Screenshot_20200703-111659_Adobe%20Acrobat.jpg

Cool. Looks like a nicely specced unit. Interesting you can run 2 strings per tracker...

I think it's the biggest single phase inverter for domestic use. I think it's much better than getting 2 x 5kw inverters in parallel.

Victron do a 15KVA single phase Quattro

The Rolls Royce of inverters. At over R90k it's a bit too rich for me. That's without the other items needed to get it setup.

I wouldn't mind swapping my 5kva multiplus for an 8kva quattro

This was the issue I had when my girlfriend innocently ordered our 3kVa :unsure: We can run another 3kVa in parallel but it would have been more cost effective and easier to just get a 5kVa in the long run. A neighbour up the road has an 8kVa Quattro and runs her entire house off of it with PylonTech batteries and around 20 PV panels.

The quattro is nice because you can connect your generator into it, and charge your batteries off that if there's LS and no sun.
 
So I'm getting a small little 950w genny to power the stuff in the lounge and trying to organise some batteries to sort out my inverter for the study.
