What this means
- The maker's rating. The most current each maker states the product charges at.
- Size it to the system. A controller rated for more amps than your panels make adds headroom, not speed.
- Amps at the battery. A rating is at the battery's voltage, so the same amps carry twice the watts at 24 V.
