What to do if my Kaco Powador 3200 is active but does not feed into the grid even when the insolation is sufficient?
- R
  reyesmaryAug 16, 2025
  If a fault such as line failure, overtemperature, or overload causes a feed-in interruption, the Kaco Inverter will check the line parameters for a period. The time it takes to switch back on may vary by country according to standards and regulations and can take several minutes. If the inverter shuts down regularly over several weeks (more than 10 times per day), contact your solar installer. Consult the fault signals for an explanation of the display error texts.

Why is my Kaco Powador 3200 active but not feeding into the grid?
- R
  Richard AllenAug 19, 2025
  The generator voltage or power from the solar modules may be too low to feed in, especially after sunrise, at sunset, or in bad weather. Also, the line voltage or PV array voltage may not be stable. The Kaco Inverter checks the line parameters before feed-in begins, and the switch-on time varies by country according to applicable standards and regulations and can take several minutes.

What to do if my Kaco Inverter stops supplying power to the grid shortly after being switched on?
- G
  Grace MercadoAug 22, 2025
  If the Kaco Inverter feeds into the grid for only a few seconds before switching off again, and shows that the power being fed into the grid is between 0 and 5 W, and the inverter is receiving sufficient generator power, the grid separation relay is likely faulty. Contact your solar installer.

What to do if the display of my Kaco Inverter is blank and the LEDs do not light up?
- M
  Mariah TravisAug 26, 2025
  The Kaco Inverter may be in night shutdown mode because the PV array voltage is below the minimum feed-in voltage. You can switch on the inverter via the night start-up key to view the measured values. A grid failure will also cause the display to go blank and feed-in to stop. Wait until the public low-voltage grid is available again. If the display does not light up during normal daytime hours, please contact your solar installer.

What to do if my Kaco Inverter trips the line fuse?
- N
  Nicholas ConradAug 28, 2025
  The capacity of the line fuse might be too low, or there may be damage to the Kaco Inverter’s hardware. The capacity of the inverter’s pre-fuse should be somewhat higher than the maximum feed-in current because the inverter can exceed its rated current for a short period in cases of high insolation. If the line fuse trips immediately when the inverter switches to feed-in mode, the inverter’s hardware is probably damaged. Contact your solar installer.

Why does my Kaco Inverter display an impossible daily peak value?
- J
  justin92Aug 31, 2025
  The inverter may display an erroneous daily peak value due to faults in the grid voltage. However, the Kaco Inverter continues to operate as normal without losses to the yield. The value is reset overnight. To immediately reset the value, switch the inverter off and on again by disconnecting it from the grid and switching off the DC.

Why is my Kaco Powador 3200 making noise?
- D
  Desiree DanielsSep 3, 2025
  The Kaco Inverter may emit audible noises due to particular ambient conditions or if Power Boost mode is activated. Line interference or failure, dynamic weather conditions, strong insolation, or resonances with grid conditions can be determining factors. People with sensitive hearing may hear the high-frequency hum caused by the inverter’s operating frequency. Such noise emissions do not affect the operation of the inverter, nor can they lead to loss of efficiency, failure, damage, or a shortening of the unit’s service life. When Power Boost mode is activated, noise emission is normal and should only be activated in environments where the operating noise is acceptable.

What to do if additional devices connected via the potential-free contact of my Kaco Inverter suddenly start up?
- D
  Derek Johnson Jr.Sep 6, 2025
  If the ”Relay 33” function is not activated, the potential-free contact functions as a fault signal relay and indicates errors. If devices provided for the ”Relay 33” function are connected to the Kaco Inverter via the contact, they can still start up when the inverter experiences an error. If you deactivate the ”Relay 33” function, disconnect devices from the inverter that were connected for this function.
P

Why don't the daily energy yields of my Kaco Powador 3200 correspond with the yields on the energy supply company’s feed-in meter?
- I
  icastroSep 9, 2025
  The measuring elements on the Kaco Inverter have been selected to ensure maximum solar yields. Due to tolerances, the daily yields displayed on the inverter may deviate from the values on your supply grid operator’s feed-in meter by up to 15%.
T
Taylor McdowellSep 12, 2025
Why doesn't my Kaco Inverter feed in the maximum power into the low-voltage grid?
- W
  wattsbradleySep 12, 2025
  The temperature inside the Kaco Inverter may be too high, causing the power to be reduced to prevent damage. The inverter limits the power starting from an internal temperature of 75°C and levels off between 75°C and 80°C. Ensure sufficient cooling of the unit, as an internal temperature of 85°C is only reached if convection cooling is impeded by external factors, like covering the cooling fins.
