I've got a 10A pwm and a10A mppt, both by the same manufacturer, the mppt uses up to 4mA more than the pwm
Really 4mA, that's impossibly low. The microcontroller would consume more than 4mA, let alone any LEDs, LCDs, voltage divider resistors. All MPPT charge controllers I've looked at over the last couple of years consume 60 to 150 mA from the battery, which is nothing like as low as 4mA.
My PWM5 kits used 1mA from the battery, and that's about the lowest I've ever seen for functional charge controller.
