What are packages?
Packages are pre-defined groups/quantities of products known to work well together.
Under each product you will see other variants with '0' quantity, these may be suitable alternatives depending on your requirements but please ensure you understand the implications before amending a package.
Off-grid solar package to power AC loads and incorporate back-up diesel generator - ideal for remote homes.
An optional PV solar system can be incorporated to generate sufficient energy over spring/summer/autumn months with only occasional diesel use. The generator will be required more in winter - depending upon sunlight and load requirements.
Normally, loads are run from the inverter which is kept charged by the PV solar array. If the batteries become low or loads required are above a level which the inverter can sustain, then the inverter will signal the generator to start, once it is up to speed loads are transferred to the Genset and the inverter then operates as a battery charger to replenish the batteries. There is no break in supply during changeover.
The system can be programmed so that the generator will run at certain times of the day, or that it will not run unless battery is very flat.

Sunny Island Battery/Inverter Breaker
Double pole circuit breakers. These protect the DC cables between batteries and inverters against overcurrent and short-circuit and allow easy isolation for installation or maintenance of the inverters.
For use between battery and inverter as positive and negative leads. Flexible stranded, rubber double insulated, copper
wire with colour coded solid copper crimped terminal lugs. Terminals have 8 or 10 mm diameter stud mounting holes.
Price per cable.
Rolls 5000 Series
These heavy duty batteries are designed for unsurpassed repeated deep cycling service in renewable energy applications. Thick plate design with high density active material and increased liquid reserve. Several 2V cells are pre-assembled together to give higher voltage blocks. These in turn are connected to form a battery bank with appropriate voltage and capacity. Unique battery design features dual container construction. Removable cells are fitted with a durable case giving double protection against breakage or leakage. Easy on-site assembly with no special tools or skills requires. Supplied fully charged with inter-connectors. Self Discharge: ~2-3% per month.
Sunny Island Temperature Sensor
Used with the Master inverter of each cluster with lead acid batteries to ensure correct battery charging.
