2. Product features
This product is designed for charging energy storage system in outdoor sunlight. It is easy to
connect, convenient for transportation and maintenance.
 Foldable solar panel is lightweight and compact shaped, with an integrated magnetic carrying
handle /magnetic bracket which makes it easy to open and close. The support stand offered
with solar panel is suitable for outdoor carrying and use.
 Solar panel is encapsulated of FR-4 glass fibre sheet substrate + EVA + ETFE protective film
lamination, its lifespan could be up to 10 years.
 Produced with high-efficiency grade A monocrystalline silicon cells, the photovoltaic efficiency
of the cells is more than 22.6%.
 Waterproof and dirt-resistant, easy to clean.
 Suitable for charging energy storage batteries with rated voltage DC48-72V (need to connect
PV charging controller separately).
 Has a certain degree of drop resistance. As 400W solar panel is heavier and can only
withstand a drop height of 0.3 meters or less. Do not hit the front of the solar panel to sharp
objects to avoid damage on the internal solar cells.
 Standard cable length is 0.5m, PV connector is MC4.
 With waterproof fabric and process, it can be used under raining.
Note: It should not contact with seawater and other conductive/corrosive liquid, which may
lead to internal short circuit. In case of this happens, please rinse the product surface with
clean water and dry it)

4.2 Operation Instruction
 The solar panel should be placed in direct sunlight and adjusted to the appropriate angle to
receive light for maximum power generation.
 This product is suitable for charging portable energy storage power supply equipment with
rated voltage DC 48-70V (need to be with built-in solar charging protection) or battery.
Warning: Do not connect the solar panels directly to charge the battery. PV charging
controller must be installed to protect the battery from overcharging or to prevent the
wrong connection which may cause damage or personnel injury. If the charged device is an
integrated energy storage machine, please follow its instruction to connect the solar panel.
 Ensure the correct connection of positive / negative poles to PV charging controller / energy
storage system.
 Check the specificaton, power, current, voltage of PV charging controller / battery / energy
storage system, ensure these values are within the limit of solar panel, otherwise it may cuase
damages and other results.
 The voltage of solar panel under sunlight has exceeded the human body safety voltage.
 Warning: To prevent electric shock, do not contact or short-circuit the solar panel when solar
panel is working on the sunlight.
 Warning: To precent electric shock, stop use the solar panel if it is damaged.
 To use it carefully, it is strictly prohibited to heavily drop, press, impact the solar panel
otherwise cells would be damaged.
