I'm having a strange problem with my heart 3000 inverter/charger when charging batteries from my genset. When I'm connected to shore power the charging current will be as high as 90 amps being put into the bank and the charging voltage will quickly rise up to 14.50 volts and all is normal. When I run the genset which is 5.5 kw the charging voltage does rise but very slowly and only up to 13.9 and the charging current stays around 30 amps. Now my shore power is only a 30 amp service and I have run this setup on just a 20amp source. As I said the genset is 5.5kw and I believe that adds up to about a 50 amp service, and I have no problems running any of my 120 volt systems including a pc so I know it cannot be a cycle problem. It doesn't seem to be a lack of current output from the genset as it acts the same if I run any other loads or just trying to charge batteries. I have a link 2000 that monitors the system and for example yesterday when I charged the house bank that consist of 4 trojan 105 that were only discharged down to 60 amphours used and the battery voltage was still 12.5 before charging and it took over two hours to bring the bank up to 13.80 volts and still around 20 amp hr used. The power share on the charger is set the same for both shore power and genset power. Any ideas?
