Had to run the Honda 2000 generator 45 min. a couple times a day just to keep them out of the red.
After taking measurements in the breaker panel and finding everything 'seemed' ok, I noticed what looks to be a blown capacitor in the lower section of the breaker panel (under the pantry). What is this? Is this the charge controller? Inverter? Not much as far as a schematic on this that I can find.
Any help to let me know what's going on here, if it's causing the rapid discharge, and how to repair or replace it would be so much appreciated!
The device located below your breaker panel is your converter. It has a single stage output and will very likely destroy your batteries due to improper charge voltage in very short order. I would replace it as soon as possible with a PD-4655 from Progressive Dynamics, which is a direct replacement.

As for your batteries, your original Interstates were Group 24, which means that they had a capacity of 80 amp/hours each for a total of 160 amp/hours. Since it is suggested to not draw lead based batteries much below 50%, that gives you usable battery capacity of 80 amp/hours.

Optimas are the same physical size as Group 24 batteries but due to their spiral design and the voids between the '6 pack', they only provide 55 amp/hours. with 2, you get 110 total amp/hours. Compare this to the 160 amp/hours that you originally had, and you can see that you have drastically decreased your battery capacity by 40% using Optima batteries.

Despite their limited capacity, they were once considered a good battery. That perception has changed recently, as the are now made in China! Check some of the recent comments on the Web.

We can't seem to get the batteries at full charge even running several hours. Also, where do we find the sleeve extender for the battery box to make it taller for using 6v batteries? We had a horse trailer that we built our own box and used 4 golf cart batteries and it would last for days. We loved it, but on this trailer there is absolutely no room to expand the batteries without building a whole new box and adding lots of weight to the front. Any suggestions? We aren't sure if our converter is a single stage or not. Thanks!
Would your converter benefit from TWO EU2000i generators ... wouldn't think so ... that is the load that an AC unit would be. Lew - please ...?

Battery & Generator Questions

The reply that I posted previously is included below. I use aluminum tubing to make the battery box riser, 1" X 1-1/2" and rivet it to the top battery box flange. The box cover ( removed) is then re-riveted to the new aluminum.

Sorry, but I can't find a photo if this mod.

QUOTE=lewster;1677261]Your batteries are not holding charge if your voltage is dropping that quickly. They are probably a victim of your OEM single stage converter/charger. Be sure to upgrade the converter to a 3-stage unit before replacing your batteries.

BTW, I use aluminum square tube as a riser for installing golf cart batteries. 1" X 1-1/2"

then Buy a Inverter/Charger with a auto transfer switch .Wire the split panel 1 side have all big load that you don't want to feed with inverter M.W ,Frig and AC. The other side has all the outlets and is fed through the inverter/charger with pass through load to all outlets and will transfer auto when no shore power. What i want is my inverter to feed all plugs not the big stuff . So you have to split the load. has anyone used this panel ? With all the engineers around here I am sure someone is going to tell me you can't do it this way . Trailer 05 25 ccd.
Just finished getting my new split panel and new inverter installed with auto transfer switch . Half the panel has AC, fridge,and microwave other half has all 120 outlets had to run separate 120 circuit to the fridge. Chose the Ames over the Magnum solely on cost my 2000 watt pure sine with remote display was 700 and some change. Have to get the fabric to redo the couch frame and figure out where to install remote display. Here's a before and after photos.
