BatteryProtect65

Hi,
Please can someone assist us in advising how the BatteryProtect65 derates at over 50degC?

Ideally, has Victron provided a graph or table to show this at 60 & 70degC?
Otherwise is this available for the BP-100 or BP-220?

Alternatively, is there a product which will operate the same as the BP65 but rated for 60+degC temperatures?

Installation is in North WA on a remote site, so high temperatures in an outdoor enclosure are expected,

Full load: -40 °C to +40 °C (up to 60% of nominal load at 50 °C)

So derating is 40% for 10C over 40C, I would expect a further 40% for the next 10C, giving only 20% of the rated capacity. Either use a larger unit to encompass the high temperature derating, or arrange a ventilation fan to try to cool the enclosure.. High temperatures will lead to reduced time to failure.
