When charging from the generator, the Xantrex cut-out trips if incoming AC amps (power share) are set at greater than 5 amps, on the remote panel. Thus the charge rate is so low it will take all day to chage the house batteries. The batteries are new this year. The generator produces AC current happily. The generator alternator is working properly. What should I do to discover what is wrong?
