A compact 12V panel built for trickle charging and small off-grid jobs. The Victron BlueSolar 20W keeps a battery healthy and topped up — ideal for stored vehicles, boats, gate and camera setups, or as a maintenance charger — with genuine Victron build quality in a tiny footprint.
Reliable maintenance charge in North Queensland sun
Rated at 20W with 1.09A of maximum-power current, this 36-cell panel provides a steady trickle to keep a 12V battery from going flat. Victron's low −0.45%/°C temperature coefficient means it keeps working through hot, high-UV Townsville days rather than fading once it warms up.
Engineered to last
High-transmission tempered glass, a corrosion-resistant anodised aluminium frame, and an IP65 weatherproof junction box with bypass diodes — the same standard that runs through the entire BlueSolar range.
