  1. I am not familiar with the Infini Plus 10KW inverter, but most inverters disconnect from the grid when the grid voltage drops below a threshold value (e.g. 190Vac). This feature causes your inverter to operate in "Islanding mode" until the grid voltage returns to a normal voltage range. The low grid voltage is most likely caused by many people turning on ovens , geysers etc in the early evening - since this loads the local transformer in the street. The LED bulbs that glow slightly - is an unrelated issue. This is normally caused when you have a dimmer module controlling the LEDs - since
  2. I think this may be a Firmware issue - see https://community.victronenergy.com/questions/45673/victron-smart-solar-15035-charging-shutoff-malfunc.html Have you tried updating the firmware?
  3. This sounds like an intermittent USB connection issue. Have you tried another cable? [Edit] Also worth trying to clean the USB contacts using some alcohol and a thin cotton-swab.
  4. A 1000V protector is going to offer no protection until the voltage rises to just over 1000V. You should be okay if your MPPT is built to withstand this voltage - otherwise select an overvoltage protector that is as close to the absolute max of your PV string voltage. The Citel part "DS240-350DC" is rated for normal operation at 350Vdc and absolute max of 460Vdc, so may be borderline for your application (I am not sure if your "400V" is normal operating voltage or absolute max).

  6. I suspect they will work okay, but I have never used them. A quick check of the specs show that they have a Neutral connection, so should be able to operate more reliably than the old-style dimmer modules (without Neutral connection). The Neutral allows them to remain powered even when the output to the light is turned off or dimmed right down to zero.
  7. Hi @Muchachos Some dimmer modules (e.g. the type covered in blue heat-shrink) can flicker, or even turn off, if there is noise or dips on the mains supply. I recommend changing the dimmer module to the "Shuttle" brand (see http://shuttlelighting.com/) - these dimmers work very well, especially with LED downlighters.
  8. Hi @isetech A great source of info is available in the following pdf https://www.victronenergy.com/upload/documents/Wiring-Unlimited-EN.pdf
  9. A lot depends on whether you are looking for individual LiFePO4 Cells or a whole 12V/24V/48V battery with integrated BMS? "Reasonable" is also a rather relative term! .
  10. I think the key to this is that one should provide separate channels for different services (e.g. AC wiring and DC Wiring) where the channels ensure both physical separation and an insulation barrier between the different services. See the following extract from SANS 10142-1:2017 Ed2. I believe that the split-trunking, as mentioned in my previous post, meets these requirements by implementing two separate channels.
  11. I am not aware of any officially published standard that says this. There was some discussion about routing solar cables in metal conduit when running over longer distances (e.g. between buildings etc.). The split trunking is widely used for routing AC and DC cables, in solar installations, in many countries.
  12. Another option to consider is "split trunking". This is rectangular trunking that is fitted with one (or more) internal dividers - so separating the AC wiring from other wiring (DC , LAN cabling etc.). I have used the Efapel 10-Series trunking that I got at AC-DC. See https://www.efapel.com/en/products/cable-trunkings/10-series-distribution. This is a bit more expensive than regular trunking, but looks way more professional. You can buy a range of corner, t-piece and end-plates that make this very easy to work with.
  13. I use Citel DS240-130DC for surge protection on my PV Panels. This has a max DC operating voltage of 180V, but they have other voltages versions available. I use Citel DS240S-230/G for surge protection on the AC connections to my inverter. This is rated at max operating voltage of 255Vac. I purchased both of these from Rubicon just over two years ago. Note: Ideally you want to choose a protector that is rated slightly above your maximum panel/string voltage, but not too high - otherwise it offers less effective protection. [Edit] This protection is more than adequate for
  14. I wonder if the fan is installed correctly and not possibly reversed? It is quite easy to remove the front cover to check this.
  15. The "overload" warnings only mean that the AC loads are larger than the Inverter maximum power output. In this case the power difference is sourced from the Mains input. As far as I know, this is quite normal in an ESS setup and is purely "informative". The temperature warnings are not normal and should be investigated.
