Congrats. A nice steady voltage during use, quick charge time.
440w with 200a should work nicely.
Edit:
I just came across this for the PD9245 (what you have?)
PD9245CV 9200 - The full rated load is available for load, battery charging or both. When functioning as a regulated
battery charger the converter has a nominal voltage. output of 13.6 VDC for 12 volt models. The system is designed to sense voltage on the battery and automatically selects one of three operating modes (normal, boost and storage) to provide the correct charge level to the batteries.
BOOST MODE: If the converter senses that the
battery voltage has dropped below a preset level the output voltage is increased to approximately 14.4 VDC to rapidly recharge the battery.
NORMAL MODE: Output voltage set at approximately 13.6 VDC.
STORAGE MODE: When the converter senses that
there has been no significant battery usage for 30 hours the output voltage is reduced to 13.2 VDC for minimal water usage. When in storage mode the microprocessor automatically increases the output voltage to 14.4 VDC for approximately 15 minutes every 21 hours to help prevent sulfation of the battery plates.
If you stay out of the storage mode it doesn't look so bad as a charger.
