Back-up Generator – Direct Energy Use
If a back-up generator is specified in the system configuration, the energy generated by
the back-up generator and the energy used directly by the appliances is identified. With
direct current appliances, the alternating current is converted to direct current by the
battery charger.
Back-up Generator - Energy
The energy generated by the back-up generator includes direct energy consumption and
the energy used to charge the battery.
Back-up Generator – Fuel Consumption
If a back-up generator is used, the annual fuel requirement needs to be specified. The fuel
consumption is calculated from the energy generated by the back-up generator and the
specific fuel requirement entered.
Battery - Charge
The total energy going into the battery (or the batteries) is shown. If the system is
simulated without a back-up generator, this corresponds to the solar energy charge.
Battery –Charge, Solar
For systems with a back-up generator, the portion of the charge that comes from solar
energy is given separately. The difference from the total charge comes from the back-up
generator’s portion.
Battery – Charge Condition
The battery’s charge condition at the start of simulation can be defined in the system
configuration (default = 30%)
Battery – Content, Back-up Generator (After Simulation)
This value appears only when a back-up generator is used. It describes the proportion of
energy produced by the back-up generator that is available in the battery at the end of the
simulation period.
Battery – Content, Solar (After Simulation)
The proportion of solar energy available in the battery at the end of the simulation period
is given.
Battery - Discharge
The total energy from the battery (or the batteries) is shown. If the system is simulated
without a back-up generator, this corresponds to the discharge of solar energy.
