I know this is an old post and the email is no longer valid but does anyone have contact info for the guy who supplied the parts for Mike?

Champion Model 46565 3500/4000w with remote start
7 months ago
I bought a Champion3500w generator with remote start. I have an OutBack FlexMax7500 and an Aims 4000w 24v Inverter/Charger with a 2 wire AGS. How can I connect the Aims to the Champion. Wiring here confuses me but i figure someone here as wired the generator to an AGS before.

Has anyone combined these units? I just got the Flexmax and Mate and it seems it can connect to an outback inverter, was hoping it could connect to the aims as well.

Just to be clear, Are you using the controller amp rating or the load amp rating? A 40A controller does not mean the "Load" circuit can handle 40A

This is one option. Probably my favorite is a whizbang jr and midnite classic charge control combo, not cheap.



I have the classic 150 on my main array. Perhaps I should give midnite a call and get the wizbang jr to go with it

If you are curious, a battery monitor is a good addition. You could track state of charge in percentage, amp hours in and out and the difference between the two, at a glance.



Any recommendations on an inexpensive but effective one.

Hi Guys,
Thanks for taking the time to reply to this thread. The PVWatts Calculator lists us at 6.37 this month and going up from here to 8.09 for June and down to 5.79 for Oct.  The lowest is 4.11 in Dec but this system will not be used as much by then. As for wether or not we use power in the daytime, as originally stated this is a secondary array, not the primary. My primary is a 24v system with 3000 watts in the array and a 3600AH (Surrette) battery bank. We are in the process of building the cottage up by the road and are at the point where we are spending time there more at night, but not were we are ready to move freezers and such and therefore not the main array at this point. The 7 batteries are brand new (installed 4 days ago). Once we have completely moved into the cottage, this array will be moved into the livestock area where it will be used to power the 12 security lights up there and a small water pump for watering the chickens, turkeys, goats and the cow so it will only be drawing out 1000w a day. At only 20% drain on its capacity these batteries will last far longer than a year or two. Right now my issue is getting through the next 5-6 weeks until we are ready to finalize the move up to the cottage and take the main array with us. As for the SOC under a load, this is the first time I have encountered that idea. Any clue where I might find that info? Seems as though that would be a great resource to share with my friends here in the valley as many of them are finally seeing there is more to solar than overpriced Harbor Freight "complete" (junk) systems.

Oh and only the 1900w or 190wph is passing through the inverter, pump and security lights are 12v so run direct. while i am above the 10% inverter capacity, it not by much lol

Hi David, Thanks for the quick reply. They are Duracell 27DC Marine and RV. Rated 90ah@20hrs. I am not concerned with the charging side of the problem because I can throw another panel at it to widen the gap. However when starting the night with what I know to be full batteries or at least reading 99% on the controller and 12.8 on the meter, I should have enough to run 10 hours, right? The inverter is a new PowerDrive 1500w. not the most efficient but far from the worst. The only thing I can come up with is perhaps I wired the batteries up wrong. Currently I have a single string with the sensing wire on the middle battery. Charging is positive on battery 1 and neg on battery 7 and I am pulling it out neg on 1 and positive on 7.  Perhaps add another battery and run 2 strings? I figured the meter should be in the middle of the bank in case charging was not even but the inverter and the meter read the same voltage for the most part. sometimes the meter reads .1v less (12.5 on inverter and 12.4 on meter) but only for a few minutes.
