Jousto’s pathway: Explore instant pricing → design it properly → installer verification. Then (where selected), Jousto EMS options support monitoring, alerts and automation readiness.

  • DC-coupled architecture: fewer conversions for strong real-world efficiency and higher usable solar.
  • Modular HV storage: flexible sizing for households that want an upgrade path.
  • Three-phase capable: backup options available with required Fronius switching hardware (design dependent).
  • Durability focus: engineered for long service life and demanding climates.
  • Jousto EMS options: monitoring, alerts and optimisation support after install — not just on install day.
