Thanks for the reply @glort.  The setup we currently have is operating successfully now for 4 years, weíve been recording the input and ouput from the system and we are running just from solar alone for 9 months of year.  However we would like to bring this to completion i.e. fully off grid. 

Yes we operate the home on 240v.  The battery bank is 24v as is the inverter.  The victron inverter offers the ability to take a feed from the generator and direct it to the house, any excess power is directed from the Victron inverter to be used to restore the battery bank tapering the charge until it goes to full capacity before automatically shutting down the generator and goes back to normal operation, drawing power from the battery bank.

Yes the 120amp charging is overkill, but we plan to expand the small battery bank in time.

We had used a 2kw inverter but it kept failing and shutting down as when heating/water pumps kicked in the draw was too much on the 2kw inverter.  The 5kw inverter offered the charging option as was not available in a smaller sized outut from this company.

Despite the apparent lack of sun, Ireland is a prime country to operate solar as we donít get extremes of sunlight/temperatures often, that reduce the efficiency of the output of the solar, the lower temperatures mean that we donít often have to contend with fans operating on charge controllers to dissipate heat.

We have the wind turbine already, itís secondhand, and as part of the purchase, we are to be shown how to service and maintain it and its from a reputable manufacturer (

During the 3 months that the solar panels don't absorb enough energy, there is only a small deficit, we average an input of .25 to 1.5 kwh, so the turbine doesn't need to max to cover the shortfall.  We only require a minimum of 2 - 3kwh per day to cover, and 4 -5 on days when we run the washing machine.

We have a 8m tower with a weather station in operation and it measures the wind speed and direction and from a year of measurements we are confident it will fill the void during the periods that there is insufficent sunlight.

If  you need any further images, don't hesitate to ask.  Thanks for your help.

Hi Guys

I'm a newbie to the forum.  I purchased a Lister ST2 air cooled with 7kVA generator, 7 years ago, a good price at 700Euro.  My plan was always to integrate it into an off grid electrical system, to that end we have installed a 4kW solar array and a 1kW windturbine is being added by the end of the Summer.  We have a 800Ah battery bank and at present, with just the solar array, it runs the house for 9/12 months of the year, hoping with the addition of the wind turbine this allow us to run the house off grid for 12/12 with the exception of approximately 2 weeks in the year when there is practically no sun or wind, this is where the Lister will come into its own.

IrishLights, decommissioned this generator, when they automated many lighthouses around the coast, converting them to Solar.  The generator has done very few hours, and starts easily on the first turn of the crank.

The plan for the Lister is to take the output from the generator and feed it into a 5kW inverter, which will charge the battery bank at up to 120Amps and the remaining power will power the house, when the generator is running.  A battery monitor will be programmed to trigger an ATS signal when the batteries drop to 70% and start the engine.

I have sourced this generator box to replace the orignal startup control box, which was not available when I purchased the Lister. 

This was the recommended module for the Lister here:

It will come with 2 bypass power relays 12V 40A to operate the starter motor and fuel solenoid valve. The module will use the existing starter motor and fuel solenoid. I understand these must be present on the generator and in working order (starter motor & fuel solenoid). The module has an auto start input which could also be used for ATS connection from the battery monitor e.g. trigger startup at 70% battery level.

I have attached pictures of the current electrics on the generator and hoping someone will know how I can wire the system, to achieve this.  I'm also about to purchase 2 x 12v (24v in total) to start the engine.  I'm willing to offer money, up to 200e to anyone who can help me get the engine automated and integrated into the current system.
