Trusted Expertise
Yardley Energy Systems + Jakiper
Premium Power. Proven Reliability. Real Australian Results.
At Yardley Energy Systems, we don’t just choose any battery partner — we choose the ones that have proven themselves in the real world. That’s why our systems are built around the Jakiper PRO Series — the same batteries trusted and praised by OGG, one of Australia’s most respected off‑grid installers.
OGG has installed Jakiper PRO units for over five years, with:
Zero failures
Zero call‑backs
Zero customer complaints
He’s stoked with them — and so are we.
Jakiper’s engineering quality, stainless hardware, rock‑solid BMS, and true server‑rack construction make them the perfect backbone for the YES Series of hybrid power systems.
