I think you have a very effective system


Thanks. I followed the advice on the forum here for how to do the wiring etc. JiminDenver gave us all a good steer towards this 230w panel with an Eco-Worthy controller combo.

Got more amps this afternoon with the sun higher. Same panel/ambient temps as this morning but now panel Isc is 8.87 (rated 8.3) so insolation is more.

INPUT- 28.9v x 7.3a = 211w
OUTPUT- 12.7v x 16.4a (wheee!)= 208w

Calculation: 211-208=3 and 3/211 = 1.42% so efficiency is 98.6%
