What is Riso low error?

What is the meaning of the Riso Low Error? According to the ABB / Power One Aurora operators manual, Riso Low indicates that the inverter has detected low insulation resistance on the DC side of your solar power system; this is typically not a problem with the inverter, but rather with the DC circuit connected to the inverter.

Can a low Riso inverter start if it rains?

Can't expect the guy to rush around to my house the moment it rains to try and catch the fault. The low Riso problem has been getting worse. Most days during July and August the inverter cannot start for at least half an hour due to low Riso.

How much power does a riso inverter use?

Both inverters are at 20 MΩ for riso, but ileak is 4 mA on one of them, and alternating between 4-6 mA on the other. This is in the evening, while generating nothing, during the last hour before they power down for the night. No recent rain (a couple of light sprinkles but barely noticeable)
