We have 4 6V Deep Cycle flooded 260A so 520A at 12v. If they are discharged to say 60% what is the most A I can charge them with ? they have got temperature proper on them. My Magnum hybrid inverter can charge at op to 125A I believe. The Progressive charger is 45A. My Honda EUI 3000 generates was stolen and are debating about replacing with the Honda Eui 2200. Rather than the 3000. We have installed the soft start to our air conditioner.Frank.

Well, assuming you have quality lugs and thick cabling, they would probably easily take 100 amps or more at that level of discharge. In fact they might even draw the max charge current of 125 amps from the your inverter-charger briefly. I have two 6v batteries with #4awg wiring that is short in length. When I have discharged them to about 60 percent they will draw the max Prog dynamics converter output of 45 amps easily. I charge them with a honda eu2000i. That honda generator could probably run a PD 60 amp converter at full output no problem.I don't know the specs of your inverter charger, but chances are it could overload the honda 2000 when batteries are discharged that far. However, there might be some settings on your inverter-charger that could prevent that. The only way to know is to try it out.if your inverter-charger is this model 'MSH3012', there may be a way to program the settings to limit max shore power amps to a level the honda can provide continuously (under 15A AC).

So looking at 156 amps or perhaps 130 amps.Your generator supplies VA and that means you can run more amps if the charger is PF corrected instead of the usual 0.7 PF. ISTR the Magnum is PF corrected. The PD is not.I have been running 50-90s with my four battery bank using a 100 amp PF corrected charger along with a 55 amp non-PF charger, which maxes out my Honda 3000 for VA. Your real question is whether you can run the Magnum 125 on the 2200 Honda, and whether that will give you a short enough generator run time to do your 50-90 (60-90 in the OP scenario.)ISTR the Magnum has an adjustable input which reduces the DC output, so you could run the Magnum with the 2200, but I don't know what the DC output would be. Forget about running the PD in addition unless you have a 3000 or two of those 2200s in parallel.If you need more info on comparative times to do a 50-90 b y charging rates on that size of battery bank, I have an "ugly graph" I can inflict on the forum, but you may have seen that a few times already :)

Usually its about 30% of the c/20 rate. What make batteries do you have?520ah @ 30% = 156ampedit....BFL beat me to it!!!;)

Trojan T145s? Trojan says 10 to 13% See Page 17 http://www.trojanbattery.com/pdf/TrojanBattery_UsersGuide.pdf

The Honda 2200 will put 80 to 100 amps into that battery through the Magnum as I believe it is power factor corrected.

Something to consider about the Honda 3000 generator. Two Honda 2200 generators cost the same amount of money. Two 2200 can run 3600 rated watts while the 3000 is rated at 2800 watts. More importantly, its easier to move two small generators. And they take about the same amount of space.

Ok it looks like back to the 3000.
Thanks.

Don't forget to de-rate for heat. Both for power and then safety of the machinery.

What is the NET consumption difference between the 2200 and 3000 with the load at, say, 1700 RPM. The 3,000 of course will idle down further.

This is not weighed with net weight or purchase price which of course will be higher. Be a shame to find out a new purchase has *almost* enough power.

Gas now A$ 1.60 l
What about the Honda 2200?

Gas on the way up A$ 1.50 at the pump.
Back to the generator. I thought that many had posted running on the 2000 and that the soft start had pretty mutch elemitadet this and as the 2200 has higher ratings and larger engine this was a no problem, in Australia we don’t camp at high altitude maybe 1000-2000 feet mostly lower but it gets hot inland in the 100+ so the question is it likely to be ok with the 2200 or not as I will have to bye it in the states and bring it back to Australia as no sellers will send to Australia and it has to be 60Hz to work with my inverter.

Yeah I was too LAY ZEE to look it up...

Venezuela is ONE CENT US per LITER

Fiji is Four Dollars Twenty Nine Cents per liter

Canada $1.18 (remember US Dollars per Liter)

Australia $1.08 per liter

Mexico $1.02

USA $0.86

Ecuador $0.39

Hi Mex,

Gas in Oz is cheaper than in Canada right now.

The day any of the oriental generators can deliver full advertised watts continuously into an inductive based load -- I will fall over.

When hungry my 4 Rolls L16 batteries gobble between 310 to 315 saturated absorbsion amperes.

Hi BFL13,

Microair equipped would be "maybe at sea level". They recommend 2500 va for reliable starting.
