  1. I they should have the right specs in the box. This is the Product parameters
  2. Code 13 is a Warning indicator. Solar charger stops due to high PV voltage. Maximum voltage should be on the sticker on the side of the inverter. What PV voltage is displayed on the display panel.
  3. Recommended panel installation configuration for this inverter.
  4. The installation specifications : Max. PV Array voltage Open Circuit Voltage should never not be exceeded. If the voltage does exceed the max voltage your inverter is not safe. I would remove a panel as was suggested .I dont have the knowledge of the components of the inverter to give advise. If it was my installation and the voltage was within specifications I would swop the wires of the arrays to check if the inverter is faulty.
  5. Measures the voltage at the circuitbreaker supplying the MPPT. If the reading is to high the MPPT cannot bring it down. This overvoltage will damage the MPPT. It is normal for the voltage to rise to Open circuit voltage of the panels if the battery is full. No current is taken from the panels If the battery is full. When battery is charging current is draw and the voltage go down.
  6. What do you have to do if the inverter is changed from a low voltage MPPT to the new high one voltage. Can the strings be changed from parallel to series at the combinerbox or do you rewire the lot.
  7. @Danie834 The BMS has a config page where you must select the Inverter brand connected to the S-volt battery. Was this done. You can also contact S-volt South Africa.
  8. Hi Danie I dont know the Max 8kW. I am using a old 5kW inverter. There is no Rs 485 cable to the battery. The battery settings of the Axpert is set on User. The charging settings is done on the inverter. I have set the Pack full charge voltage and pack fullcharge current setting on the BMS using the PbmsTools HS1.0.6 download. The battery charges normal and Amps taper off when full and stop charging. All this is controlled by the BMS .The display on the battery - BMS will display - Full. I have a 24v battery so use the specs I sent.The BMS will stop charging a minute or 2 after reaching the settings. Use the interface Definition for the Rs485 cable.
  9. The Axpert was installed 2015 and still growing.
  10. I have no knowledge of firmware updates. Glad your Axpert is stil alive
  11. Battery absorb must be 52.5v .S Volt charging specs
  12. Your charging rates is very high.If you lower the rate the cells will be more balanced .You have to connect to the BMS and see if it is setup correct for 15 cells and to see if the cells are balancing. See the post on the forum and watch the video. Product Options and Reviews Svolt106AH Review Battery(5.43kWh/16 cells. Lower the charging for 15 cells and full pack voltage to 52.5v
  13. That seems to be a warning indicator and not a fault. Battery equalization.
