RNG Support,
Why do the started kits include a POSITIVE ground PWM controller?
Everything we tend to use is Negative grounded. I assume you can float the
ground or Positive ground the unit. My concern is, if you do POSITIVE ground,
when you connect an Inverter, and it has a NEGATIVE ground.... won't that be a problem?
My system is all renogy except the inverter which is a Power Bright PW2300-12.
I was curious of the design for the PWM Positive ground system and why that is used?
I'm working on a few designs that are OFF Grid but have the flexibility to provide disconnect
functionality of the Power company A/C and feed multiphase A/C from the OFF grid inverter.
I didn't want to confuse matters with the "Positive Ground". From reading about your
Solar controllers it appears the MPPT are negative grounded, a little more expensive, but
may be a more robust controller.
thanks for you help!
