  1. This is awesome. Really like the Blynk interface
  2. I don’t think it is possible, with the standard packages available, because of the Raspberry Pi’s ARM architecture (Not x86 or x64).
  3. Has anyone made any progress with regards to Tshwane and the intolerant Conlog meters?
  4. I agree with the OP’s original statement to a certain degree, but not for the purposes of communicating charge and discharge current limits. The biggest issue that I have experienced is the ability to control or manage your systems energy based on accurate battery SOC (%). Now the problem lies in, where do you obtain this information from? 1st prize is of course, the battery BMS. But often times either the battery does not support any form of native communication with the inverter or vice versa, the inverter does not support any type of communication available from the battery. The fall back is to control the system through battery voltage derived SOC. This, unfortunately, is typically quite inaccurate. A work around though is available in the form of Victron’s range of high precision battery monitors, the BMV700/702/712. These devices are battery agnostic because they measure energy throughput. This way you can calculate the true SOC of any battery, provided you setup the BMV correctly. You then simply need to make sure that you can pass the information from the BMV to the inverter or control system so that your system is now managed based on accurate SOC. In an advanced hybrid power system, you need an accurate battery monitor. This either needs to be of the form of communication to the BMS or a 3rd party external device like a Victron BMV700.

    10kv infini 3ph

    I recommend taking a short video of the symptom, specifically of the screen pictogram, so we can evaluate all the conditions present.
  6. Hi All, Just wanted to find out what others experience have been with this battery? We have 2 units that were installed over 2-years ago, paired to a GoodWe GW5048 ES Hybrid Inverter. The inverter was setup with the specific profile for 2 x GCL E-KwBe 5.6kWh lithium batteries. We have had frequent problems with both batteries. The first occasion they were returned to the supplier who supposedly had to do "BMS" repair service on both units. Both of them are now faulty again, and I was just wondering if anyone had experienced something similar?
  7. ICC is compatible with the 10kW InfiniSolar inverter. What mode are you running the inverters in? Is the PV equally distributed across both inverters?
  8. It all depends what mode you're going to be running the Infini 10 in. If you run it in grid tie with backup mode, it'll tolerate the overload (Grid relay closed) but if you run it in off grid mode then it might trip and/or try revert to AC/utility bypass.
  9. The manual describes warnings and errors. The two are different, please ensure you are able to differentiate between the two. You are most likely experiencing warning 11. This is an overload warning. If an overload condition is maintained, specifically in inverter mode (Off-Grid), the inverter will disable the output to protect itself. The output is illustrated by the light-bulb in the bottom right hand corner.
  10. During inverter operation (No Grid input) the machine is limited to 3.3kW per phase (3 Outputs allowing up to 10kW of total output). This would be the case if the inverter is programmed for "Off-Grid" mode. If Grid-Tie with Backup "Mode" is used, then the inverter is able to "blend" power from it's input sources - Grid, PV & Battery and has something called the "Grid Relay" closed and is able to handle quite a lot more throughput/load than the rated 3.3kW per phase. In off-grid mode, if the load exceeds 3.3kW on a phase, the inverter will bypass load delivery to utility supply (if present) in order to avoid an overload condition. This involves relay position change and will have an associated transfer time. The operating mode is very dependent on many of the programmable settings in SolarPower and requires quite a thorough understanding/experience to achieve the desired operating condition.
  11. Here's a basic "mixture" guideline from Pylontech. US2000B US2000 PLUS US3000 Difference and Mixture Installation.pdf
  12. I e-mailed Voltronic about Pylontech BMS communication support on a late 2018 manufactured InfiniSolar 4kW Super. Their response was that the model was currently not supported. I have not inquired about the 3kW, 5kW and 10kW InfiniSolar Inverters.
  13. Please describe your objective of the Hybrid Power System and your equipment and then we can advise re: appropriate settings. I'm not sure what you mean when you say "switch the output from grid to solar"
  14. Grid-Tie with Backup (I), Grid-Tie with Backup (II) etc... ? Screenshots of the settings would allow faster troubleshooting. Has the DB been split into essential and non-essential loads, and the essential loads connected to the output of the inverter? Is the Inverter Output Enabled (Light-bulb bottom right-hand corner)?
  15. There are multiple modes in which the InfiniSolar range of inverters can operate. In Grid-Tie with Backup mode, you can de-select the checkbox that says "Export to Grid".
