FAQ'S
How many amps does a 300W solar blanket produce?
A 300W solar blanket typically produces around 10 amps per hour in ideal sunlight conditions. However, output can vary depending on sunlight intensity, angle, and temperature. Pairing it with a quality MPPT regulator ensures maximum efficiency and safe charging for your 12V batteries.
How long does it take a 300W solar blanket to charge a 12V battery?
Charging times depend on the battery’s capacity and state of charge. For example, a 300W solar blanket can recharge a 100Ah deep-cycle battery from 50% to full in roughly 10 hours of strong sunlight when used with an efficient solar controller.
What can I run with a 300W solar blanket?
A 300W solar blanket can comfortably power camping fridges, lights, fans, small inverters, and device chargers. It can also help maintain or recharge dual-battery systems in caravans, camper trailers, and 4WDs — making it ideal for longer off-grid trips or setups with higher energy demand.
Can I connect my 300W solar blanket directly to a battery?
It’s not recommended to connect a solar blanket directly to a battery. Always use a solar charge controller (preferably MPPT) between the solar blanket and battery to regulate voltage and prevent overcharging or damage.
What type of battery works best with a 300W solar blanket?
A 300W blanket works well with most 12V AGM, Gel, Calcium, or Lithium (LiFePO₄) batteries. For best results, match the blanket output and controller settings to your battery chemistry and capacity.
Is the 300W solar blanket suitable for caravans and 4WD setups?
Absolutely. This high-output solar blanket is ideal for caravans, camper trailers, 4WDs, and boats, where you need efficient off-grid charging for longer trips or multiple appliances.
