I'm in the process of renovating an old farmhouse. All the wiring and plumbing was stripped out.

I'll likely leave it off grid.

I've replaced the roof and put 16 panels up. Plan to build a a lean-to extension at the back - will put another 16 panels up there.

Thinking of going with a 12kw or possibly even 16kw inverter.

Always heard that Sunsynk had the better interface / app, but that service wasn't great.

Lots changed with Sunsynk distribution over the past year or two. I heard they were setting up a new warehouse in SA?

What are your thoughts on Sunsynk / Deye at the moment? Deye would prob come in a couple of grand cheaper - not enough to influence the decision much..

6-7 years ago Sunsynk was top of the pops, the darling of installers and homeowners alike. That honeymoon period has expired and lots of water has passed under the bridge. Their South African country manager (David Drake at the time) made written promises of loaner units for repairs / swop-out under warranty, which were later dishonored and rescinded, and which left a bad taste in many people's mouths.

The Sunsynk is not a bad inverter at all, I have one that hasn't skipped a beat for the past 6+ years. I have another that had a calibration issue since day one, which ought to have been returned under warranty, but I haven't done it (since 4 years ago) because it would inconvenience the client to be without a unit for the 6-8 weeks that it takes to decommission, ship, await repairs, reship and re-install. It's OK, does what it says on the box, but today it is hardly worth the price premium.

If I were to turn the clock back, in hindsight the Deye would have been the better choice (at the time).

If I were to do the same installations again today, I would rather install a Solis S6 series, far better support and warranty, and far more advanced technically than any Deye / Sunsynk, as well as a far cheaper price. Moreover they are a Tier-1 manufacturer with an excellent global reputation vs the Sunsynk / Deye's tier-2/3 status (at best).

Let me put it this way: If my own personal Sunsynk blows up today, I wouldn't even shop around, I would gladly replace it with a Solis S6 in a heartbeat. The 16K Solis S6 made its debut in April this year, the 5, 6, 8 and 12K quite a few months earlier than that. Check out Powerforumstore's reviews on the S6 range, they are great.

Why consider hybrid inverters if you don't need them?

@DylanP As above, no need for grid-tied hybrid inverters if staying off-grid, maybe two 6kW Deye off-grid inverters, and put the savings towards batteries.

I need to agree with @Yellow Measure .

I personally have been in contact with solis support many times, most recently with my parallel setup. The installer made a mistake installing the second one, they got on the phone with me diagnosing the issue. I would never consider any other brand.

Flexibility, if / when adding another possibly larger inverter which could fulfil the role of grid.

The power landscape could look totally different in years to come. Not it looks good to be off grid but if wheeling/virtual networks take off those with space might want to be on TOU and buy during off peak to sell during peak.

Hybrids would serve one well. Just a thought to have the extra functionality.

Agreed.

And if the feedback rates improve, those with large battery banks and oversized arrays could consider selling or wheeling themselves.
