Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Any problem running my Honda EU20i into my Hybrid?
Expecting a power outage on Wednesday. 8:00 to 4:00pm. Think they are moving us from 11 to 22kV...
At times like this I usually just power my office 1.5kV UPS off the Genny to get thru the day.
Still pretty warm up here & have a tonne of Prawns, Oysters & fish on the outdoor freezer & fridge. Not keen on it defrosting.
The total load on the inverter is usually about 3kV by midday with air on etc, so was hoping the Genny could provide it's 1.7kV & the solar the rest.
It can make up around the 2.5-3.2kV mark from 11:00 on if the day's good.
Presume the inverter could cause the Honda to hunt if it was in Eco Mode, but normal should be OK?
Thanks
Phil.

Do you mean have your Grid Tie Inverter sync to your little genny to take some load ?

I am glad someone asked, initially I thought he was talking about a car.There are only 10 types of people in the world: those who understand binary, and those who don't.

Sorry, Hybrid Inverter not Car....
Inverter operates in Hybrid off grid mode.
IE it's configured to pass grid power thru to meet load requirements if not enough solar to feed the output.
Morning load is less that 1000w, with solar before 10:00 under 500W.
As the day progresses solar output can peak at 3000+ w, and load reaches 4kW+ if I don't load shed.
It will only draw from batteries if no AC input is present, but only have 80Ah @ 48V of batteries present, so get around 1/2 hour runtime.
Would be good to be able to keep more than just my office up during the 8 hour outage.

The Honda Inverter generator should be making power as clean as or even cleaner than the grid. Can you set how much power the inverter/charger draws from each input? My old Trace would do that so if the load exceeded the generators ability it would support it with power from the batteries.There are only 10 types of people in the world: those who understand binary, and those who don't.

No, can't set quotas on the inputs, but can change the priority so if solar decreases it first supplements the load with batteries before drawing more from the grid.
Other thing I mentioned, I assume the Honda would need to run at full revs not eco load as both it & the inverter would be trying to juggle where to get input supply from.

If it is only for a day I would not bother with economy mode especially if you have big loads to power. If the generator is hunting around it might cost a lot more than a bit extra fuel.There are only 10 types of people in the world: those who understand binary, and those who don't.

Input Would may be called "Maximum Ac Charge Current" or something different.
However The one I use is pass-through mode and and will use use all the AC to power the hose (total load) and charge the battery at the same time. If its overloads the generator it will reject it and go to battery, then after a short time it will reconnect to the generator
Yours will be a little different.

My Parameters page is a bit different.
It's in Off-Grid (II) Mode
AC charge setting doesn't seem to limit what it can pull from the mains either.
"Feeding Grid Power Calibration" is hard to find any decent explanation for, and get the impression it's not related to feeding back to the grid.
"Generator as Source", not real sure about that one either.

Very watery mention in the software manual.

The AC charge current will be on top of whatever AC loads you have running at the time so keep that in mind with what the generator can produce.There are only 10 types of people in the world: those who understand binary, and those who don't.

Good point. 10A - 500 Watts +.
Shouldn't need it though as the batteries are fully charged before 8:00am.
Unfortunately there seems to be a firmware issue with these where at very low solar levels; about 50 Watts, they seem to draw on the batteries to power their internals, not the grid.
Leads to a bit of unwanted battery drain at dawn & around dusk.

10A = 2400W if it is the AC, can't read those setting pages.There are only 10 types of people in the world: those who understand binary, and those who don't.

What! you need glasses? Downloaded the pdf manual and the screen shots are no better. (if it was the correct one) After reading the off-grid section 1-2-3 I can see why its confusing.
Looks like the generator could ether supply the power to run the house direct (not ideal) or work as a DC supply (charger) which would work along with the solar and batteries, should be easier on the genny that way. Not sure, must be the only one that would do this.
I know for sure the HS model wont.
A note on gennys: some small ones don't have the neutral and earth joined, some do, have seen the little honda running ok on these.

I couldn't be bothered going into the fine details of those Inverters Aaron.
Keep in mind too generators with just a capacitor for regulation put out a nasty 3rd harmonic and are not suitable for anything electronic. The Honda Inverter generator that Phil has should be as good or better than the grid.There are only 10 types of people in the world: those who understand binary, and those who don't.
