How to Connect 4 pcs of SP420 Solar Panels to the FOSSiBOT F3600 Portable Power Station
Since its release, the FOSSiBOT F3600 has been loved by many consumers because of its 3840Wh massive capacity, 3600W high output and support for 2000W solar charging.The FOSSiBOT SP420 solar panel of 420W is the best companion of the F3600to harness clean, green, and renewable energy for various outdoor activities. The F3600 supports up to 4 simultaneous connections to gain enough power in 2 hours. So what’s the best connection way to gain fastest charging speed? By connecting in series or in parallel?
We know that in a series circuit, the current is the same, the voltage is added;The voltage in the parallel circuit is the same, and the current is added.The SP420 has an max working voltage of 32V and a maximum operating current of 13.1A.The maximum current of the XT90 interface of the F3600 supports 20A. Under this premise, we can calculate the charging power of the corresponding connection mode.
Connecting SP420 Solar Panels in Series
When you choose to connect four SP420 solar panels in series, it means connecting their positive and negative electrodes in turn to form a chain. This increases the overall voltage, suitable for scenarios requiring long-distance power transmission. With 4 pieces of SP420 panels connected in series, the maximum output power would be: (32V +32+32+32) * 13.1A = 1676.8W.
Connecting SP420 Solar Panels in Parallel
Parallel connection is also a common connection method, that is, connecting the positive terminals together and the negative terminals together, forming a parallel circuit. This connection can increase the current and is suitable for situations where the current output needs to be increased. In parallel, the maximum output power of the 4 SP420 solar panels is: (13.1+13.1+13.1+13.1)*32=1676.8W. However, in parallel connection, the maximum input power that the F3600 can receive is limited by its XT90 port to 20A. So the maximum input power that the F3600 can receive is 20A*32V=640W.
Notice about charging portable power station with solar panels
A.Ensure correct polarityconnection to avoid short circuits or other safety issues.
B.Keep the solar panel surface clean to maximize sunlight absorption.
C.Secure connections between the F3600 and the solar panels to prevent interruptions or instability.
D.Avoid submerging the solar panels in liquid or prolonged exposure to rain, despite their IP67 waterproof rating.
E.Adjust the installation angle of the panels according to season and geographic location for optimal sunlight exposure and efficiency.
In conclusion, connecting 4 SP420 solar panels to the FOSSiBOT F3600 can replenish enough power within just over 2 hours, providing sustainable energy for various outdoor activities. This powerful combination serves as a reliable energy source for home backup, saving on electricity bills, or enhancing outdoor experiences such as camping or RV trips. With its high capacity, output, and fast charging capabilities, the F3600 paired with SP420 panels ensures you always have the energy you need, wherever you go.
