Inverter and generator

If I was to have a 2000W inverter charger instaled in over FW that currently has 600V of solar and 2 240A 6V dep sycle batteries and want to get a generator for backup and running air conditioning 15000BTUwill it be better to get 2 2000V or a 3000V and hove much charging will I be able to get out of it, or one 2000V or 2 2000V or a 3000V.
I am willing to get 2 more batterys if it has to be, currently the FW charger is a 45 A 3 stage progressives Intely converter with I build charge wizard. Thanks
Frank.

  • I properly asked it wrong, what sort of charger will it run, 75A, 100A as in Magna PSV inverter charger, they say they use about 25% les pover.
  • Under ideal conditions 13 amps at sea level. For every 1000 feet there may be a loss of 100 watts (0.83 amps).

    At 5000 feet that loss totals 500 watts so the generator is going to only output 1100 watts continuous or about 9.5 amps.

  • I would look at the "1 2000 watt and a 3000 watt hybrid inverter with load support with two more batteries" option. The Honda 2k will *almost* run the AC at altitude, with the inverter covering the startup surge, and any shortfall, The 600 watts of solar on the roof will keep the inverter running far longer. I would get the "75 amp PF corrected charger" BFL13 talked about as well.
  • I believe that the OP also wants to run their 15K A/C ... using the same generator that they choose for battery maintenance.

    I vote for a couple of Honda 2000's, as with this combination you have generator backup redundancy. If ever one Honda can't be started, then at the least the OP has some 120V AC generator capability still available by using the other Honda. Only one Honda is needed for pretty good battery charging, so with only one Honda operating the OP can keep the batteries topped up - just not camp with the 15K A/C usable.
  • Your single Honda 2000 can run a 60 amp Non-PF corrected charger or a 75 amp PF corrected charger. It will struggle with a higher amp non-PF corrected charger.

    If your inverter-charger has (typically for a 2000w inverter size) a 100 amp PF corrected charger, the single Honda 2000 will struggle badly, especially at any altitude.

    So that limits your options to a 3000 or a pair of 2000s. You get more power from the two 2000s and they are handier physically to deal with going camping. Both 2000s will make more noise than the single 3000 if the difference there is an issue.
  • Ok thanks so far yes I meant W. Yes I was considering a Magnum inverter charger is this what you refer to as hybrid I understand this load-share with batteries for large loads like microwave and air conditioner. I was wondering hove mana amps the 2000W (1600W) continues Honda can supply I am fine with 2 more batteries for a total of 480W
    Frank.
  • I recommend a Victron or Magnum power combining inverter and four+ batteries.
    Run with one Honda 2000 with extended run fuel tank.
  • Choices
    1 3000 watt

    2 2000 watt

    1 2000 watt and a 3000 watt hybrid inverter with load support with two more batteries
  • Hi Frank
    First lets be clear do you really mean Volts or Watts. Most generators are rated in watts so I'm going to assume that is what you mean. What you need to do is figure how many watts you need for normal operation with the AC running then you can choose the correct generator or combination there of. I have a emerald 5000 and can run two AC and the microwave without problems.
