That was one of the indirect questions, so your answer is helpful. - I have small mecer inverter and already get annoyed for the noise it makes.
Very good points, and information around size and weight. Thank you. Seems that I should rather move the inverter + Batteries to a different room.
You right, I was thinking of mounting it above, but not directly above the DB Board, but then I wouldn't be able to access the screen or buttons.
How difficult is it to configure the Inverter? I can get my electrician to wire it up to the DB, but I doubt he have experience with solar installations.
If I look at buying the equipment, and do a DIY installation, it seems that I would "save" around R20k.
