Solar Charger 300W

This MPPT Boost controller solar charger is customizable, which will allow you to recharge any battery from 24V to 72V regardless of its technology. Indeed, this charger is compatible with lithium batteries (LiMn and LiFePO4) but also with lead, gel, NiMh, NiCd batteries. MPPT technology is the technology that will bring you the best charging efficiency. The "boost controller" integrated into the charger allows you to use a panel output voltage lower than the voltage of the battery to be recharged.

You can therefore recharge a 24V, 36V, 48V, 60V or 72V lithium battery with only one 12V solar panel. The speed of charging will depend on the power of the panel and the sunshine conditions. For example, you can recharge a 500Wh battery (36V 14Ah) in 5 hours of sunshine with a 12V 100Wc panel. Note that this charger is not waterproof.

The MPPT technology with integrated boost controller allows you to use a simple 12V solar panel to recharge a 24V, 36V, 48V, 52V, 60V or 72V battery, which will allow you to reduce the surface of your installation and save money.

However, depending on the voltage and the capacity of the battery to be recharged, it will be possible to combine several photovoltaic panels in series or in parallel, the whole thing being that the output voltage of the panel or panels is always below the low-voltage cutoff threshold of the battery to be recharged.

For example, if you are charging a 36V LiFePO4 battery with this charger, you can use only one 12V or 24V panel or two 12V panels in series, but you will not be able to use two 24V panels in series.

The output current of the panel or all panels must not be more than 300W, otherwise the charger will go to safety.

The panel input voltage must be lower than the battery output voltage.
