INTELLIGENT APPLIANCE CONTROLCONDITIONS AND RULES FOR ON/OFF CONTROLOptimisation for operation time for appliances with flexibility of operation…

> Run, when the sun shines (ecological optimum)

> Run, when cost of energy is lowest (economical optimum)

Conditions for operation start:

> Definition of a suitable time window

> Appliance MUST run within time window… (compulsory)

> Appliance CAN run, if [condition] ... (optional)

> Sequence of priority in case of multiple appliances control


BASIC SOLUTION FOR INTELLIGENT ENERGY MANAGEMENT

Plant monitoring

> How much electricity is being generated and stored right now?

> How much electricity is being drawn from the grid?

> How much PV energy have I produced this month?

> Was the operation of my plant interrupted during the day?

> Are all the inverters working equally well?

Sunny Home Manager – The all-around expert

Energy management

> Get the weather forecast for the next days

> Schedule the loads for the next hours/days at high PV production

Energy monitoring

> What devices are currently in operation?

> How much PV energy is being generated right now, and how much is available?

> Was I independent of the electricity grid today?

FLEXIBLE STORAGE SYSTEM

> Increasing the Self-Consumption Rate from

30% to 65%*

> Usage of Solar Energy 24/7

> Switch your household appliances on at the

right moment

> Maximum flexibility with Battery Capacity,

Battery Type and Battery Power

* All numbers are based on an energy production and consumption of

5,000kWh per year, a usable battery capacity of 5kWh and utilisation

of a SUNNY HOME MANAGER


SUNNY PORTAL -FOR ENERGY FLOW VISUALISATION

> The analysis page displays the energy balance

for the selected time period and provides the

user with a variety analysis tools.

> Energy balance diagrams enable the user

understand how much of the local consumption

is covered by self-produced and temporarily

stored PV power.
