Solar System Estimator

Estimate the inverter capacity of a solar system based on the appliances you want to power and how you use them.

This is a preliminary sizing tool. It does not calculate system pricing, battery capacity or solar module capacity. Final system design should be confirmed by a qualified PMK TechFlux Global engineer.

1. Select Your Appliances

Add the appliances you expect to use. Set the expected backup time for the selected loads.

hours
How long you expect the selected loads to be supported by the solar system.

Appliance Quantity Power (W) Remove
Important: Appliance power ratings shown by default are preliminary estimates. If you know the actual rating on your appliance nameplate, replace the default value before calculating.

2. Your Preliminary System Assessment

The result below is based on your selected loads, PMK's preliminary 3× load-sizing approach, and practical AC sizing guidance.

Estimated Daily Energy 0 kWh/day
Estimated Running Load 0 kW
Primary Recommendation 0 kVA
Air-conditioning load: Air conditioners are high-demand loads. The recommended capacity takes PMK's practical AC sizing guidance into account.

Recommended System

0 kVA

Recommended when you want greater capacity and fewer restrictions on simultaneous appliance use.

Select this option to continue.

Option B — Load-Managed System

0 kVA

A lower capacity option that requires disciplined load management.

Select this option to continue.

Why load management matters:

A smaller inverter must not be operated beyond its safe capacity. Running several high-power appliances simultaneously can cause overloads, protective shutdowns, poor performance and, depending on the equipment and operating conditions, damage to system components. PMK recommends proper load management whenever a lower-capacity system is selected.

3. Are You Satisfied With This Result?

You selected a 0 kVA option. If the result looks right, continue to request a quotation. If you want to add or remove appliances, return to the appliance list and recalculate.
