heliOS

heliOS enables installers to generate professional battery storage quotes in under two minutes using real-time pricing and margin calculations. Advanced ROI modelling tools allow installers to demonstrate projected customer savings, EV charging benefits, tariff optimisation, and long-term payback periods through clear, data-driven projections.

Branded PDF proposals can be generated instantly, helping installers present polished, customer-ready documents that reinforce trust and professionalism. A key differentiator is heliOS’s automated MCS compliance system, which generates MIS-3002 and MCS 012 compliant documentation with minimal manual input.

For non-MCS installers, the platform offers an Umbrella Scheme, allowing installations to be submitted for assessment, review, and certification—lowering the barrier to entry for newer businesses.
