Ikster

i feel uneasy too. I will assemble the system this weekend and give it a run. I will update this forum.
The manufacturing and assembly from Tesup is questionable but I have started fixing their wrongs like loose bolts and misaligned parts.
The alternator itself seems quite robust but the charge controller seems more toyish in construction.
I will reinforce the tower as much as possible and use the proper guy wires to stabilize the platform.
Lets see what happens...fingers crossed. 

Hi guys. If I may add to this topic. I have a Kwikot geyser and I installed a 1.5kW twin PTC element as a replacement for the old resistive type element and the results is great.
Less power consumed and the water still gets to temperature at about the same time a conventional element takes to heat up the water.
The other part of the PTC element is a DC element rated at 950watts so it can run off a 48V battery.
Its a good way to save on energy. Geyserwise is the place I got mine from.
