Sleep Integration at Night?

[gedger]

Most Inverters go to sleep at night to save power and will not respond to polls. I was wondering whether there was anyway to get the Integration to back off the polling rate until it comes back on line? At the moment I have mine set to 20 seconds, so I was thinking that if 3 polls failed then drop down 10 minutes polling rate. My inverter comes on-line as soon as there is light even if it's generating less power than it's using so shouldn't miss any data.
