Yellow Measure

Hello and welcome to Powerforum. Your 8K SS is capable of charging at 190A, and the R100s should be capable of accepting 100A each, so 200A when in parallel. The SS is compatible with the Revov's BMS using CANBus protocol 0. You should be charging at well over 7Kw with that array on a sunny day (depending of course on your loads, orientation and azimuth of panels etc.). Check your CANBus comms cable (Inverter to master battery) and master to slave battery link. If you don't spot any issues, please share your LiBMS screen, as well as battery setup screens?

Where did you get the Dyness Powerbrick rated at 300A? Dyness Global site has the Powerbrick and Powerbrick Plus (which is not available in SA), both at 14.336kWh and 140A / 0.5C (Continuous). Yes, it can peak at 300A, but not continuous. Why? My 32kWh bank feeds a 5k inverter.

OP has an 8kW Multiplus last time I checked, 2x Knyee in parallel is ample: will deliver 9.6kW @100A with peaks of 19.2kW at 200A. It's an interesting limitation, and I suspect that Knyee are being ultra conservative. I have 2x 16.08kWh HinaESS PowerGem Max, which is the white-labelled version of the Knyee, was also supplied by @Powerforum Store and its datasheet states 200A continuous max. discharge per unit.

It should not be too much of a hassle if not, can easily be made up. Nothing special about MC4 solar panel connectors or the coaxial power connector (also known as a DC barrel connector).

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

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

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the time) made written promises of loaner units for repairs / swop-out under warranty, which were later dishonored and rescinded, and which left a bad taste in many people's mouths.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.

You make a good point, I was seeing it as an off-grid portable point solution, and it can only function as an off-grid inverter if it is Franken-monstered into a "solar house". Not impossible, but potentially troublesome. It's still overpriced though, compared to the far more extensible and feature-rich the Hinen / Knyee combo at R18,342.50: 11.4kW solar input vs 6.5kW ; 2x low amperage MPPT vs 1x high amperage MPPT; Parallel capable; Hybrid connection possible vs off-grid; Integrated Type II DC SPD & Type III AC SPD (amazing!); Built-in aerosol fire extinguisher; 10-Year Warranty vs 5 on inverter only.

No floodlights, security cameras, electric fence and alarm systems running 01H30-04H00? 🤔

This is cheaper, same size battery, half the wattage but more than enough for TV and laptop.

You reminded me of something quite important, which I forgot: Whilst house-hunting during 2019, I made a point of only viewing properties with: a clear W-->N<--E view; and 0 degree azimuth (10-15 degrees max either side); and a roof that can take 24+ panels. I did not have to look long for a suitable home, and having made my wishlist upfront helped a lot.

I have a Sunsynk 5K, 6kWp on roof since 2020, and recently upgraded storage to 32K Hina (Knyee white-label), been off-grid since January 2026. I have been optimising usage and current drain over the past 6 years: Outdoor heatpump for hot water; Gas stove, oven is still AC, but I built a Pizza oven outside (and a whole outdoor kitchen too!); Added 2x Inverter aircons (24000 + 18000 BTU); Gas heater; Slowly migrated current hungry devices, like firewall / router / NAS / security cameras / NVR to fanless low current models; Don't operate Class-A amplifiers continuously, or moved to Class-D. Next on the list is the fridge freezer, eyeing a Bosch AAA+ model. Optimising a power budget is basically the same as running a bank account: You either create more income, or you cut / replace expenses, or a combination.

Indeed, even the Tesla Powerwall 3 has a charge rating of 0.37C and a discharge rating of 0.85C.
