    This high efficiency waterproof 250w polycrystalline solar panel is perfect for all off-grid installations on caravans, campervans, motorhomes and boats for charging leisure battery banks or for standalone household with batteries.
    It can also be used for lighting applications and for back up power with and inverters.
    The has been manufactured to the highest standards, thoroughly tested and labelled with a unique serial number for further quality control and better warranty protection.
    The is fitted with 2×0.9m of cable specially designed for panels to carry currents with negligible loss (4mm cross section).
    The comes with Mc4 connectors which be for easy connectivity to your existing for linking several together or for connecting 4.0mm extension cable.
    This positive tolerance, means that its output is actually higher than (the is typically in the range 252w-255w).
    specifications: Peak power: Maximum voltage: 30.60v current: 8.17a Open circuit 36.30v Short 8.71a tolerance: 0/+3% Dimensions: 164 x 99 x 3.5 cm Weight: 19 kg Mounting for ease of of single core Male and female Note: this requires a 20a Mppt charge controller for a 12v battery, or a regular Pwm for a 24v battery.
