Max charger wattage

Hello, everyone.

I've been waxing engineering in respect to my BlueSolar 75/10. I've studied user manual's spec list, and I've come to understand that the max battery output is 290(29V*10A) Watts on a 24v battery system. With that established, I've also been playing around with the charge settings on the Victron app, and in doing so, I noticed I can set float voltage as high as ~35v or so and that got me wondering.

Is the max power output dependent on when the bulk charge ends/float voltage starts? And if so, would that indicate that the charger could output as much as 348(34.78V*10A) Watts if the battery was appropriate?


Thanks for you help, and knowledge. :)

Interesting question. Assuming that the product does work how you want/expect it to work, you may have an oddball voltage for the battery bank. Everything else connected to the battery will also need to work for that voltage range.

That is correct. It’s a 10A charger, therefore whatever the battery voltage is x 10Amps. Keep in mind the maximum input current limit on the PV side, it’s on the spec sheet.
