  1. Money is in. Solis ZA are bringing the new Ginlong Series 6 3Ph hybrid inverters into ZA early in 2024. These have been confirmed to be able to handle unbalanced phases and as far as I can see, have 4 x MPPT. Not a lot of info on them yet. The ZA rep says they want to do some tests in ZA before they announce the products.
  2. Gave up on the bank loan. I'm sourcing funds elsewhere, and luckily for me, the delay means Solis is now launching their Series 6 inverters, which means Unbalanced Load support for the 3 phase Hybrids.
  3. Still waiting for the bank loan. To be honest, I'm still trying to decide between the R100k+ solar hybrid with no batteries and only around 5kW production and a R100k 3ph 35kW diesel generator that will solve loadshedding............
  4. Update on this: I crunched the numbers and got some quotes. It is cheaper to actually buy an oversized 3-phase hybrid inverter than to have 3 x single-phase inverters running in parallel. Pricing at this stage for a start-up system (grid-tied, no battery) are between R100k and R137k depending on components (that was before the latest price increases) That would be a 15kW inverter, as well as 10 panels to easily satisfy the minimum PV required to activate the inverter (usually between 160VDC and 180VDC depending on model). Yes, this price is quite steep but the installation is between 20% and 30%. So I decided : bugger that, I know a qualified electrician that will help me, and I'm going to do it myself. Solis S5 15.0kW Dual MPPT 3-Phase Grid Tie Inverter - R25k Solis S5 25.0kW Triple MPPT 3-Phase Grid Tie Inverter - R38k At that price difference, I'd rather go for 25kW. MUCH for flexilibility and less chance of load issues later. The problem now is solar panels. No stock anywhere and the prices are mental compared to 3 months ago. Hopefully that clears upo soon, but in the meantime I can install the inverter and make sure there is space for optional batteries later.
  5. Bit of a hijack on this thread, but I'm looking for a clamp-style (CT) power logger so that I can check the peak usage on my 3-phase supply. I don't mind if it is only a single clamp system: with loadshedding, there is ample opportunity to swap between L1, L2 and L3 Since this will be a once-off use to determine my peak loads prior to finalising my PV inverter purchase, it shouldn't break the bank. I don't mind WiFi or BT as I can use either a laptop or Android phone to access the logs. Any suggestions?
  6. Just to clarify: so a 10kW 1ph inverter to handle one of the phases, and a pair of 5kW in parallel to handle the rest?
  7. Lots to think about. Need to now check the peak load on each phase.
  8. @Steve87 : thanks for that. Another issue is that the 1ph units would also have a load limit: If I have a load of 6kW on 1 phase, do all 3 units need to be 6kW?
  9. I know. But there is a thing called phase rotation, usually handled if the units are properly in parallel. This applies to load balancing as well?
  10. OK, and how do I run my 3ph appliances off 1ph?
  11. Thanks. This one?: InfiniSolar 15kW 3 Phase Hybrid PV inverter (enway.co.za) The 10kW unit does NOT do phase balancing.....max 3.7kW per phase.
  12. Also, wouldn't the 3 x Axperts require paralleling as well as balanced phases? I have unbalanced phases and I'm not going to spend R50k sorting that out.
  13. Thanks, but I'd like to back feed to build unit credits for night time consumption.
