Here's the info I have after testing the charger and gen set. What I did first draw the battery bank down 65 amp hours used and the bank voltage after sitting idle for a hour was 12.55. Charging the batteries the actual current draw on the genset was 8.5 amps with a constant voltage of 115 volts. Then I installed the capacitor across the line side of the gen output and the effect was about the same still 8.2 amps 115 volts. The voltage going to the batteries started at 12.55 and quickly rose up to around 13.75 with the current being around 37-40 amp hrs. When the battery voltage rose up above 13.75 the amp hours started to decline until the charger went into float. This was about the same with or without the cap. installed. I should also mention the these reading stayed about the same even when I increased the load on the generator from just charging batteries up to all the 110 volt loads such as microwave, hot water heater, ac unit, pc.
Now for a couple of questions, if the charger is only drawing 8.5 amps ac I would think running a 8kw genset with just a 8-10 amp load is not good for the genset, no? I do know when I was adding up my total 110v loads it seemed to me that a 5.5 kw gen would of been more than enough power I needed.
While on the subject of charging I have to say I was very suprised with the output of the wind generator I just installed. Over the past weekend it was able to keep up the the reefer after it was down to temp. In around 25 knts of wind I was seeing as high a 5.5 amp hrs being put back into the batteries and with the wind generator up on the mizzen the noise wasn't bad at all .
