BYD Solar Battery vs. Fronius Reserva Review

The Fronius Reserva battery has finally hit the market in 2025… but is it actually better than the proven BYD solar battery? In this video, Mark and Yorick go head-to-head in a debate, breaking down everything that matters — not just marketing specs, but real-world performance, installation practicality, compliance, efficiency, and long-term reliability. If you're considering a solar battery (especially with the current rebates pushing 30–50kWh systems), this is a must-watch. 🔍 What We Cover • Design and build quality (metal vs plastic covers) • Label compliance (and why most installs get it wrong) • Maximum stack sizes (single-phase vs three-phase) • Energy density (litres per kWh explained properly) • Cooling design and longevity • Round-trip efficiency — real-world test results • Why high-voltage batteries are superior • Garage footprint and installation flexibility • Charge and discharge rates (important for VPPs & blackouts) • Proven reliability (6+ years of BYD data) • DC cable protection and Australian standards compliance If you’re installing a battery, remember: The right design depends on your loads, backup requirements, future expansion plans, garage space, and whether you’re considering VPP participation. A good consultant should design around your needs — not just sell you a spec sheet.
