WOW, this question will be common with most Solar use folks. Most all of the posts I read from those who are now into solar, seem to start small and continue to add. The question might soon come. Can the MPPT and the PWM be used in parallel for the same batt bank?? Using the 'connect to battery first idea'. I have one of each but need each for different batt/panel array.
A note to our friend in Victoria. I have the 20a PWM in use with the E/Scooters 24v system. Works like a charm. Waiting for a really bight sunny day to check the system for input to the batts. Hope the 100w panel will output as one reviewer stated, saying he experienced over 100w in total sun.
I'm waiting for the best angle to the sun chart, maybe I missing one way back somewhere.
This is some awesome challenge for the Old & Slow guy.
