Reliable, high‑speed MPPT charge control for marine, caravan and off‑grid systems; advanced monitoring and configurable charging to protect battery life.

• Ultrafast MPPT Technology: 45 A MPPT designed to deliver the highest possible energy yield and support system monitoring for optimum array performance.
• Inbuilt safety protection: protects against PV short circuit, PV reverse polarity, PV reverse current, battery reverse polarity and battery overheating via internal temperature sensor; self‑diagnostic and LED fault indicators.
• Advanced programming and monitoring: connect the optional MPPT Control panel (sold separately) or VE.Direct accessories for remote configuration and monitoring.
• Live data transmission: real‑time display of solar panel voltage, current and power; data logs: system activity for the past 30 days available to view.
• User‑defined battery charging algorithm: option to disable preset values in favour of personalised charging parameters for various battery chemistries.
• Efficiency and ratings: highest MPPT efficiency (>95%); max solar panel voltage 150 V; max solar panel power 600 W (12 V) / 1300 W (24 V) / 1950 W (36 V) / 2600 W (48 V).
