Large lots, long driveways and a lot of well pumps. Backup sizing looks different when losing power means losing water.

What we have learned here

Working in Niwot and Gunbarrel

  1. 01

    Well pumps have high starting current. A 1.5 hp submersible can surge past 7 kW, which sets the battery inverter class before daily kWh does.

  2. 02

    Detached garages and barns often have their own subpanels and sometimes their own meters, which changes both the array siting and the interconnection.

  3. 03

    Outages out here run longer than in Boulder proper, so two battery modules is a more common recommendation than one.

  4. 04

    Large, unshaded roofs with room for 10 kW DC or more. Export value rather than roof area becomes the limiting factor.
