    After doing some research, it seems that: The MPP Solar MPI 10K three-phase hybrid inverter will need an optional "Energy meter" in the form of Modbus card II inserted in the inverterโ€™s "Intelligent Slot". It does not support a simple CT coil, like many of its competitors. If you are planning to use lithium battery storage, BMS comms is important, but lithium battery support on the MPI 10K is provided by a separate BMS RS485 card, also fitted in the (singular) "Intelligent Slot". So if it is already occupied by the aforementioned, you will need to use voltage to control the inverter's knowledge of State-of-Charge (SoC), which could be inaccurate and the inverter cannot respond to BMS protection events. Edit: It does seem that there is a RS-485 BMS Box option which uses the RS-485 port on the inverter to provide BMS comms vs the card version.

    It's a very open-ended question, so before you get any answers to your questions, you need to share some information. Budget: ball-park figure. Do you plan to do the installation yourself? Are you qualified / skilled enough to do so? Do you know what your current and planned utilisation is? Do you know what loads you want to cover? What are they (in kW)? Partial coverage or full? This is 3 phase, so how are your loads currently split on the various phases? Have you planned for Storage? What technology? High voltage or low-voltage batteries? How much storage? Have you planned for generation? What technology? Solar / wind ? How much? Do you have North-facing roof space available, or are you envisaging a ground installation? These and a lot of other questions need some answers before someone can help you with the actual equipment and protection devices needed. There are many, and they all depend on your design. If I were you, I'd speak to an expert at Powerforumstore, give Wimpie or Steve a call, they can design a system for you with everything that you need, down to the last bolt and nut.
  4. Excellent choice, I doubt that you will regret it.
  5. Bump, this is still available.

  8. @Rockstar22114 any feedback? Did you come right?
  9. True. I upgraded my tiny 5K system from 10.5kWh to 32kWh storage, the difference in the past 4 months has been remarkable, as is my quality of life:
  10. I did exactly the same when I had limited storage capacity, good move.

  19. From the LiBMS screen, I can see that you have good battery comms, also that the BMS is limiting charge and discharge to 160A, for whatever reason (it may be an earlier revision of the R100 that had this limitation). Interestingly enough, I cannot get a specsheet or manual from official Revov sources, but I Iocated a Revov R100 manual that states that 30A is the recommended charge rate. https://www.manualslib.com/manual/2888737/Revov-R100.html?page=1#manual Was the LiBMS shot taken during the day, full sunlight, or at night? Can you take a shot during the day when it starts charging from PV? Also, do you have an official manual / specsheet for your Revov batteries that you can share? On the first battery screen, I see that you have set the battery to 200Ah, that is correct for the two R100s in parallel. Why did you choose 130A for charge and discharge, and not the combined maximum continuous charge amps and maximum continuous discharge amps of the two batteries in parallel? Does your revision of the R100s only allow 65A charge and discharge rates? It effectively limits your 8kw inverter to deliver only a little over 6kw when drawing from the battery at night. Is that how you want it? On the 2nd battery screen, I see that you are limiting Generator (Aux port) to charge at a maximum of 40A, and Grid charge to a maximum of 130A, yet neither are ticked to allow charge. I guess that to do not wish to charge batteries from grid or genny at all? Do you have a genny connected to the Aux? What firmware revision level are you running? Is it current? Can you provide a pic of the settings screen where this is displayed? Can you also provide a screenshot of the Battery Shutdown screen? And lastly, may be a silly question, but I have to ask it: how are your PV strings configured? 2 strings with the panels in series?
  20. 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?

  22. 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.
  23. 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.
  24. 2x 16K Knyee will cost R60,720.00 Sell the balance out of hand.

  25. 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).

  27. Agreed. And if the feedback rates improve, those with large battery banks and oversized arrays could consider selling or wheeling themselves.
  28. Flexibility, if / when adding another possibly larger inverter which could fulfil the role of grid.
