OK I have had the original charger inverter power supply working and the AGM battery is charging just fine. The problem I am having now is that the if I am running my A/C and my Microwave on shore power sometimes either or will trip the breaker. I just think the whole power supply unit is old and needs replacing. It is a Parallx 7300 Series power supply. I am thinking is it possible to change to a 50 amp supply instead of the 30?
One other question. Do these new supplies come with a fan for cooling the unit? The current one to my knowledge does not.
You are just hard headed. You keep stating Inverter. YOU DO NOT HAVE AN INVERTER, PERIOD. You have a CONVERTER integrated into what they call a Power Center. That means you have the 120 Breakers and the 12 volt fuses AND the CONVERTER in the same housing. Your problem is as the other poster stated. You are PULLING TOO MANY AMPS on your 30 amp system. The AC in 90 degree weather will pull around 13 to 14 amps. The M/W depending on its Watt rating will pull 9 to 12 amps. Refer 2 amps on 120. IF you have a water Heater that also has 120 besides LP that will pull another 12 amps. Your CONVERTER will pull anywhere from 1 to 5 amps depending on the 12 volt load in the RV. ADD any TV's or other 120 appliances and you will see you are over the 30 amp limit. Most 30 amp RV's CANNOT run a Microwave AND the roof AC at the same time. Changing the Power Center will NOT gain you any advantage. You are limited to 30 amps. Changing to a 50 amp service can be very expensive. I can find NO Parrallax info on using lead batteries versus AGM. The problem with using AGM's in place of Lead batteries is the Converter charge rate. Granted you see NO problems at this point, but usually it takes months or years for the damage to occur to AGM batteries when using a charging system NOT designed for a AGM charge rate. Doug
