Solar systems & appliances
Power designed around the life you actually run.
Explore system directions for homes, offices and critical facilities, then use the calculator to turn appliances and operating hours into a careful first-pass plan.
Choose by operating need
Three starting points. No one-size-fits-all promise.
A system is only useful when its load profile, starting currents, backup window, solar access and future growth are understood. These categories guide the conversation; the final design follows a site survey and protection review.

What changes the answer
Engineers size systems from evidence.
Appliance wattage is only the beginning. Starting current, simultaneity, duty cycles, solar resource, heat, shading, battery limits, cable runs and protection all affect a safe recommendation.
What runs together?
Coincident demand and motor surge drive inverter size.
For how long?
Daily operating hours and night share shape storage.
What can solar reach?
Roof area, orientation and shade determine yield.
What cannot stop?
Criticality and redundancy change the architecture.
Appliance thinking
Start with what must stay on.
The calculator includes practical planning presets, but always use the actual nameplate wattage where available, especially for air conditioners, pumps, freezers and workshop equipment.
Lighting
Count each fitting and its real operating window.
Motor surge
Compressors and pumps may need several times running watts to start.
Duty cycle
Refrigerators cycle; they do not draw rated power continuously.
Growth margin
Plan sensible headroom without oversizing blindly.
