For those wishing to connect to the grid you may or may not find these useful.
SELCO make generator controls, the C6200 is an auto synchroniser which will sync an AC gen supply to either another generator/ multiple generators and or the grid, either as load sharing, load balancing exporting or importing and peak shaving. http://www.selco.com/
The unit is a C6200

Also check out Basler Electric's
BE3-25A
AUTO-SYNCHRONIZER
(Single Phase)

At http://www.basler.com/html/rscrel.htm

Through imagination Ac to DC rectification and DC to AC inversion and the integration of the above units it is possible to create a common live power bus from solar wind and generators that can synch to the grid.

As a pointer to start you all off.
The most important element is a stable reference voltage and frequency... the synchronisers then synch to this in much the same way as solar or wind inverters sync to the grid.

Read the material it’s out there its free and good luck...

I don’t export to the grid, but I do have a common bus bar (power rail) that is supplied by a 5kw windmill and 4kw solar array and multiple generators that come on and share the load automatically as demand increases or unload as demand decreases..

My next move is to use GEK as a fuel source for my engines

I am unable to assist with specific questions or advise on electrical issues…seek qualified and professional help.

Good post!

I went the steps for grid connect.  It isn't easy.  Peaker Services from the Detroit area is highly recommended.  They carry the Woodward line of controls and they deal with smaller apps.

SEL inc has the 700GT but they really lack the experience in installation.

You can connect through solar/wind turbine by attaching the turbine/gen to a diesel/gas gen and spinning at a speed accepted by the inverter.

Beckwith also makes this type equipment. Woodward makes the governor controls. When I spoke with them a few years ago, they said the smallest generator that could be controlled with grid quality precision was 20kw. Below that, it's like running cruise control at 35mph.

I've wondered about connecting a Uninteruptible Power Supply in line to level out the quality of the power output. That, or some capacitors to provide a buffer for the slight rise and fall of power output.

please excuse my ignorance, but could anyone please point me in the right direction to understand what are the variables that have to be considered in order to grid tie a power pallet ?
In this thread "grid quality precision" is referred to, but I am not electrically knowledgeable enough to understand.
the rationale behind my question is that I would like to know wheter a power pallet can, other things being equal, be connected to he grid to sell electricity or use it as a battery.
If anyone feels like answering please consider I am in Europe, Italy. I believe fundamental issues are the same but maybe some things, like frequency or voltage or regulation, are likely to be different.
thank you
