I have a customer with a 3-phase InfiniSolar 10K which is giving a fault code 3 = "BUS soft start time out".  The unit is out of warranty.   The original supplier can not help me.  Does anyone know of a local business which repairs these units ?

Tried Mustek today with a similar request - I have 7 failed 10kW Infinis and the supplier is sitting on their hands. Considering flying boards in and repairing in-house. Will post f I find a solution.

Is there a the common cause for failure?

Apologies for the late reply - the last 5 months have seen all manner of investigations, speculation and assumptions. @Nicholas ended up going to Shenzhen to meet with Voltronic's head of R&D to get answers  The long and the short of it appears to be design / environmental, whereby an insulation element isolating a bank of IGBT's from their heat sink on the Main Board is rendered marginal / ineffective in the presence of dust or condensation.  Steps are being taken to upgrade the design, as well as to develop retrofit filter panels for use in dusty environments.  They have also revised firmware to increase fan operation.
