We are looking for a hybrid AC/Solar charge controller. We have a few
sites that are primarily powered by the grid on AC using a DC UPS to
keep up a 48VDC plant. Most of the equipment runs directly on the 48VDC,
with a few legacy devices running on 24VDC.
We want to augment the AC power with solar for a couple of reasons.
First, it will provide recharge for the AC during expected rolling
blackouts. Second, we can reduce the overall AC/grid costs if the solar
can provide the bulk of the power when the sun is shining. We live in a
relatively solar-friendly environment, and typicially get 5-11 hours of
usable solar per day, depending on season. We think an appropriately
sized solar/battery setup could eliminate the need for a generator.
I'd like to find an off the shelf solar controller that can take 2 power
inputs; one from solar, and one from AC (or maybe just rectified AC?).
Any help from the borg?
