mppt vs pwm
Hi, A nice little video comparing mppt vs pwm with the batteries in bulk mode. mppt vs pwm
Forum Discussion
It just occurred to me that in the video, 14.2 volts were used for charging. But if a more appropriate voltage was used, like Trojan's recommended 14.8v, that would lower the mppt's amp output even further.
So, correct me if I'm wrong, but wouldn't the numbers look more like this:
PWM:
4a (Isc), regardless of the higher charging V.
MPPT:
17.4v X 3.6a (Imp) = 62.64w / 14.8v = 4.23a
... for a gain of 5.8% (vs. 24%)
