Hi,
Yep, precision is wasted effort. 10 or 20 degrees out makes such little difference it is of academic interest only.
Even on a house it is cheaper to put in extra panels facing East or West to catch the lower sun than to put in the mechanics to track the sun.
Cheers
Jaycar had a clearance sale on over the last weekend.
I dropped in to buy a simple voltage switch kit ($7.50 vs usual $25) and noticed they had an MPPT Controller kit marked down from $140 to $80. When I asked at the checkout, the priced was halved to $40 - so I bought it. It's a design from Silicon Chip magazine - meaning I can probably repair it should it fail.
I hope it doesn’t end up in your under thread as failed to work.Quote:

I have just bought a couple of MPPT controllers to replace the PWM controllers on my boat and on my Navara and I am wondering what the "Load" connection is used for.
Fridge ??Quote:

Read the instructions.
It is just a spot/outlet to run something direct from the solar panels/controller while the sun is still making enough power - is something that is there but never used it - simply easier to let all power from the panels go to the batteries and provide power for you gear from there. If the sky clouds over the batteries still provide a buffer where power at the load point will drop off.
