I have read several reports of WFCO going 5 to 10 amps above rating if you have enough battery and actually get boost mode. Mine did before it decided to just remain in boost indefinitely.
PD seems to sag a bit and the full amp rating is not at 14.4 volts but rather 13.2 so get 10+ amps rating higher than you expect.
IOTA by all reports I have seen is regulated right to the rated amps at any voltage. 14.7 boost is a bit of a misnomer as it will shift to bulk within 15 minutes of exceeding 14.6. Although I do like the IOTA program except the float seems a bit high for a hot climate.
Powermax drops similar to IOTA but goes down to 13.6 volts. Or you can get the manually controlled version. But if going manual I would sooner have a Meanwell or similar adjustable power supply.
