HVAC and water pumps
Plant load measured before anything is sized, and run off site generation wherever it earns its keep.
The problem
Plant is a large share of most commercial load, and it is usually sized and installed without anyone measuring what it actually draws.
Electrical works for heating, cooling and pump plant across the site. Plant is a large share of most commercial load, which is why it is measured before anything is sized, and why it is often the first thing that should run off the array.
What the scope covers.
02
Pump sets and plant supply
Dedicated supplies and controls for pump sets, sized to the motor and its starting load.
03
Plant load measured before sizing
What the plant actually draws is measured before a replacement or a new supply is sized.
04
Run off site generation where it earns its keep
Plant that runs in daylight is scheduled onto the solar output, where the saving justifies the controls.
What it usually looks like

Indicative ranges. Measurement on your own plant replaces them.

How it runs, start to finish.
01
Measure the plant
The actual draw of heating, cooling and pumps is measured, not read off the nameplate.
02
Size the supply
Circuits, protection and controls are sized to that measurement and to the starting loads.
03
Install alongside
The electrical work is done by the contractor already on site, under one contract.
04
Shift the load
Where there is solar on site, daytime plant is scheduled to run from it.
Before you ask us.
Do you install split systems and heat pumps?
Yes, alongside the electrical work, with the supply and protection each unit needs.
Why measure plant before replacing it?
Nameplate ratings rarely match what plant actually draws. Measuring first avoids oversizing the new unit and its supply.
Can pumps and air conditioning run on solar?
Where they run in daylight, yes. Scheduling them onto the array's output uses more of the solar on site instead of exporting it.
