BougeRV's 200W solar panel utilizes a high-level 9BB cell design, offering a 22.8% conversion rate - the highest on the market. This design increases the cell receiving surface and reduces the covered area by 22% using a thinner ribbon, resulting in a longer service life for the solar panel. Additionally, it can charge 12V and 24/48V batteries by wiring several solar panels in series.

This battery features low-temperature cut-off protection and a self-heating function, which is critical. The low-temperature cut-off protection activates when the temperature is below 32℉, and the self-heating function kicks in when the temperature is below 33.8℉ while the battery is being charged. This means you can use the battery in colder climates or during wintertime without worrying about damage to the battery.

The BougeRV 40Amp MPPT Remote APP Control Solar Panel Regulator can only be used with photovoltaic panels as a charging source; it cannot be charged using a DC power supply.
