Thank you for the reply Plonkster.
This is a bit frustrating. I have contacted four different solar power consultants / electricians and all have agreed to come look at my system and do a paid consulting to resolve this problem.
None actually showed up for their appointments. Not one.
After re-calling them a couple of times each, it is evident that they aren't interested in taking the job but will not tell me that. I guess they are just cherry-picking which jobs they want. Does anyone know a professional solar consultant in the Cape Town area which would be interested in taking on this job? Key word there is 'professional'.
Thank you.
