BME-3P-WP-15 Twin 15Kw Hybrid Inverter Service manual. This should be relevant for the BME-3P-WP-12 as well. It will also cover the Infinisolar and other voltranic derivatives of the same model.
I battled to find this, came across it randomly when looking at another board I need to replace on my unit, so hopefully this helps some one out down the road. For some reason when you search for this, it comes up with the 30Kw inverter made by infinisolar which doesn't appear to have any relevance to this unit, the components are vastly different.
