Install New Charge Controller close to batteries

I am looking to install the New InetiPower 60Amp Charge Controller close to batteries as that is best for faster charging.

I am wondering about taking out old charge controller under stove. Can I just disconnect all wires and remove it? I was thinking that it is needed to power 12V system when we have hookups?

Then I wondering about how we charge batteries when hooked up to shore power, with relocated Charge Controller? Second Cord just to the Converter? Or how I might grab power that is part of the system when we are hooked up.

At the end of the day my goal is to:

1) Relocate Charge Controller location

2) be able to plug RV into Shore power and have batteries getting charged.

3) be able to plug RV main Plug into Champion Generator and have batteries getting charged.

4) Have New Charge Controller close to batter bank in front Storage (4 6v Trojans)

    Make sure the gen has enough VA to run the charger. A 2000w inverter gen is about maxed out with about a 70a non-PF corrected charger. The PD 80 amper is non-PF corrected. Some say they have run an 80 amp PD with a Honda 2000. I don't know how!


    Appears the 2000w should handle it.

    Specs on the Honda 2000i
    AC Output: 120V 2000W max.(16.7A)
    1600W rated (13.3A)
    Receptacles: 20A 125V Duplex

    Specs for the PD9180A
    Input: 105-130 VAC, 1,300 Watts
    Note: Requires 20 amp rated outlet
    Output: 13.6 VDC, 80 Amps

    Here we go again!!!! :(

    The PD converter has a PF of 0.7, so that "1300w" is actually 1857 VA required from the 120v power supply. Which is why they want a 20a plug in with 12 wire for it.

    The Honda "2000" has a continuous rating of 1600VA (not "watts")
  • Honda 2000va should power an 1857va device just fine.
    Honda is good for 30 minutes and by then the PD is tapering amps anyway.

    May need 1857va apparent power however the amps will be based on the 1300 watts actual power.

    Honda "2000" is not 2000VA it is rated at 1600VA and also at 13.3a (120v) where 13.3 x 120 = 1596

    Kill-A- Watt readings with a non-PF corrected 75amper doing 75 amps (constant) into a battery with voltage at 14.08 (and rising) when the charger is set to 14.8v.

    123.5v, 13.64a, 1241w, PF 0.73, 1693VA. DC Output 75 x 14.08 = 1056w and input 1241w = 85% efficiency. (Don't know why the VA is a tad higher reading than V x A.)

    An 80 amper scaled up would be 80/75 x 1690 = 1802

    It is true that some gens can initially run more than their continuous ratings. How long that would have to last depends on the charging amps wrt the AH capacity of the bank and its initial SOC. Half an hour would be with a small battery bank like a pair of 6s or a pair of 12s starting at 50%. Four batteries would be an hour in Bulk with a 70 amp charger.
