The problem with running A/C is of course the high start up surge required. Your Honda has plenty of juice to run the A/C, but not enough to manage the load during start up. The solution (hopefully) is a synchronizing inverter. Such an inverter evaluates the power needs and then synchronizes power coming from the generator with power drawn and inverted from the batteries.
So with your Honda plugged in, when the A/C startup load exceeds the Honda's output the inverter seamlessly steps in and makes up the difference from the battery bank. When the A/C cycles off and the input current
exceeds requirements, the inverter switches to battery charging
The purpose of this sort of inverter is specifically to enable a much smaller generator to work in more situations.
Sounds interesting - a syncronizing invertor. Is the article also online or just in the magazine?
I've used a Honda 2KW for over four years and love it. We use it to run a Cruiseair 5KW AC unit, or for when we use the electric
stove or coffee maker, to avoid sucking the amps out of our battery bank. The wife prefers the electric
stove over the propane stove - she's feels that it's safer.
On Eco throttle (on the Honda gen) we can run the Cruiseair AC unit at night for 8 hours on one gallon. I would like to rig it in order to suck from a larger tank to get longer run time. The colder air actually drops down into the two aft berths and keeps the saloon
very comfy. Those generators are awesome! I highly recommend them. AC's are great option to have to combat the hot Florida
summer nights and when the bugs (no-see-ums and squitos) come out.
