[RE-wrenches] Generator choice for Sunny Island

Good question – I was assuming a regular gasoline genny mostly because the
container will be moved from time to time. Whatever type of fuel, it
definitely has to be portable.

Sho you want diesel,  propane or natgas?

Nathan is more reliable as it does not require a refuel.

Hi Wrenches, especially those of you who work on off-grid projects,



We have an upcoming off-grid project where we will be powering a storage
container with electronics in it. The loads are mostly 120 volt but there
is a 240 volt heat pump that might occasionally run. We’re AC coupling the
Sunny Island with a Sunny Boy PV inverter. So, we’ll be installing a
Outback PSX-240 autoformer to bump the Sunny Island’s output from 120 to
240 volt.



We need to select a generator for backup. We need a two-wire electric start
(in order to be controlled by the Sunny Island) and preferably a generator
that is okay just running 120 volt loads since the Sunny Islands input is
only 120 volt. Something in the 3 kVA -7 kVA range should be fine.



Does anyone have experience or ideas about what kind of two-wire start
generator we might select?



Thanks,



August
