Multiple Chargers
I’m traveling and the charger has failed. Until I can get it repaired I’ll buy and use a standard auto charger. Have you used multiple chargers on a battery bank or do you know which ones work in that...

810AH bank recharging with 180A is a 22% charging rate similar to my 100a on 458AH bank. In the ugly graph above somewhere you will see it takes me about 2.5 hours to do a 50-90.
It is all proportional, so with the same 22% rate, the 810 should take about 810/458 x 2.5 = 4.4 hrs so think four and a half hours.
My 2800 Honda 3000 can do 100a of PF corrected charger plus another 50a of non-PF corrected charger before popping its breaker. This looks ominous for your 100 plus 80 unless you can organize more generators. The extra 1000 can't be combined. If you had two 40amp Vectors instead of the PD 80amper you could do 140a on the 2800 and 40a on the 1000.
I'll let you know how it goes. I can usually get 45-55a from the 1000is at sea level, but back the rate off until the generator rpm mellows a little. The 2800 has run the charger wide open at 95-127a. Might have to take the 3500 Honda to run them both at max.
Tonight with 200ah down, the PD would do 74a on it's own, but only 63a with the Magnum laying down 84a. I assume if the bank was down to 60%, they would do more. This was tested on a 20a circuit from my house with incoming voltage down to 109v.
