  1. I have a 5 year old Pylontech US3000C that's working well connected to a Must hybrid inverter that can't read the SOC - it's been operating mostly in UPS mode without any issues. I'm thinking of either adding an additional 3000C to allow for higher amp capacity. Is there any issue with connecting both a new and old pylontech battery in parallel? Should I rather sell and get a Dyness 5.12KW Lithium Battery BX51100 for almost the same price?
  2. I have a similar issue with the 5kw 48v model and a pylontech lithium battery - nothing I have tried has stopped the charge indicator. Although I don't think it has any real world impact as the battery seems to stop accepting charge once its full according to the amps display and the battery LEDs
  3. Anyone up to service an unhappy Kodak (model OFF-GRID INVERTER KING WITH UPS 5KW)?
  4. Mine seems to have gone away. It may have had something to do with very high humidity or reducing the charging amps down to 20A on the pylontech.
  5. I have a Mecer 2400VA similar to this in our complex guardhouse that provides backup power to CCTV and the comb intercom (controlling the gate access remotes). This causes a puzzling issue when the UPS is operating as the gate remotes work very intermittently and inconstantly. When the intercom system runs off its own battery or Eskom the remotes work without an issue. It seems the UPS is outputting a RF signal in the 400Mhz band blocking the remote's signal from reaching the intercom box outside. Would popping a few of these clip on ferrites on to the leads coming from and to the inverter fix this?
  6. Yes, I simulate load shedding by disconnecting Eskom for 3 hours while at home using my appliances normally. This discharges 1/3 to 1/2 of the pylontech 300C's capacity. I also bumped up the charging rate to 20A
  7. After 6 rounds of testing I haven't been able to recreate error 08. The only condition missing is the rain with the wet car parked in the garage next to the inverter. My theory is that on my inverter error 08 is triggered by condensation and/or very high relative humidity
  8. I have the same fault 08 "Inverter bus voltage too high" popping up on my Must Power PV18-5048VHM inverter with the setup below: No PV panels installed 1 x Pylontech 3000C battery without comms cable Inverter wired into the DB as a UPS for my lights and plugs Battery earth and inverter earth are connected to the DB earth No other faults or issues Mounted in garage In both cases the fault occurred at night after load shedding when the battery was recharging. After resetting the inverter it operated normally until next night. Recently I had an issue with my earth at the Eskom box causing the prepaid meter to disconnect leaving me without power until Eskom fixed the earth connection on the neutral cable outside. The second possible cause/contribution was that this was the first time in ages that I had parked my car in the garage after driving in a rain storm. The garage at at 10pm was very humid (almost steam sauna). Both faults also occurred very early in the morning when the garage cools down and there is possible condensing from the humidity. The last issue could be that I had changed the battery charging rate down from 25A to 10A and I'm experimenting with higher charging rates to see if there is any pattern
  9. Our office has a unused outback inverter in the server room and wired in to the DB we would like to get it up and running with batteries. Are there any technicians here who work on them in the Sandton area? Thanks
  10. So the sparky opened the municipal electrical box and found the earth connection was loose. Now that these connections are fixed the dips on source changeover have stopped
  11. Thank you @Coulomb I think this is a useful setup for those who would like to conserve their lead-acid batteries. The voltage dips between mode changes are causing the TV and HiFi to turn off and I have asked him to get the unit swapped with a 5kw King model, apparently they operate in a more smooth continuous mode without dips during mode changes.
  12. I'm trying to figure out the best way to figure out the best way to get a benefit out of a bad install at a relatives place. The inverter is a Mercer branded 5kw SOL-I-AX-5P with 4 * 105Ah non deep cycle batteries and 5 strings of 2 * 380w panels with panels are facing west (don't ask why). The inverter doesn't seem to blend power sources and jumps with a noticeable dip between sources, enough to turn off the HiFi, so I would prefer it not to bounce between sources Inverter specs DC input 48V 117A AC Charger Mode AC input 230V 50Hz 35A DC Output 54V Max 60A Default 30A Solar Mode max current 80A System voltage 48V DC min voltage 40V max voltage 145V VOC I'm aiming for maximum battery runtime while load shedding then using offset some utility consumption when the panels get sun. I'm thinking of using the following settings to try force the batteries to stay as full as possible and use solar as much as possible when available. 01: SOL Solar energy provides power to the loads as first priority. If solar energy is not sufficient to power all connected loads, battery energy will supply power the loads at the same time. Utility provides power to the loads only when any one condition happens: - Solar energy is not available - Battery voltage drops to either low-level warning voltage or the setting point in program 12 12: 54v Setting voltage point back to utility source when selecting “SBU priority” or “Solar first” in program 01 (currently 50v) 13: 54v Setting voltage point back to battery mode when selecting “SBU priority” or “Solar first” in program 01. (currently 54) 16: CSO Solar energy will charge battery as first priority. Utility will charge battery only when solar energy is not available.
  13. Have you noticed any issues with the transfer time with the SOL-I-AX-5P ? I'm trying to sort out my Dad's setup and the every time it changes mode the HiFi receiver turns off and all the lights noticeably blink off/on. Given this is occurring every 30 mins (even on utility power) the inverter does not seem suitable for blending in solar power
  14. I have a 5KW Must PV1800 VHM Series Inverter spec sheet Currently its only used as a battery backup with a Pylontech battery pack and working well. The settings were a bit fiddly with the LiFo battery as it cant communicate with the battery pack otherwise its working well. I hope to add a few panels soon and test the hybrid function
