Simulate battery performance

Model how each battery charges and discharges across a typical year, soaking up midday solar and topping up on cheap off-peak rates before the evening peak.

See grid imports, exports and time-of-use tariff impacts, so your team can explain battery savings in a way that customers understand.

Backup-ready single line diagrams

Pylon draws hybrid and AC-coupled configurations, battery isolation and backup circuits straight from the design you already built.

Make battery value easy to understand

See the financial impact

Whether solar is new or already installed, show how batteries, a new energy plan and off-peak charging lower the bill.

Fully managed components

Find battery storage and hybrid inverter options by capacity, brand and backup capability.
