Hi, i’m having two 12v 335 watts panels in parallel and i’m receiving a e08 error that stands for pv input over current. it should be capable of 800w?

Two 335W panels in parallel is 670W (assuming they have the same electrical specs). The Renogy spec sheet says that model RVR-40 only handles up to 520W in the 12V configuration (i.e. connected to a 12V battery bank). The 800W you mentioned is for the RVR-30 in the 24V configuration (i.e. two 12V batteries in series).

Can I disconnect the battery while the solar collector is still connected?

No, I dont think that's a good idea since they say connect batteries first the solor panels. If you was to shut ur system down, the go in reverse. Panels discount then battery.

How does the Rover measure battery capacity remaining % if it does not have a shunt? Can percent remaining be reset ?

It can not be reset unless you power it down. Mine is not very accurate.

Can this controller be used with RV converter running?

Should work fine as it operates as a 12-24V system. Mines been making free power for about 2years now and had zero issues.
