D300S PV Voltage Step Down Module
Product Information:
The D300S PV Drop Down Module is a product created by BLUETTI
Tech Team. It allows your EP500/Pro and AC300 power stations to
connect with roof/rigid solar panels for a maximum solar charging
capacity of 2400W. This module is especially useful for users who
already have installed rigid solar panels and PV grid-connected
inverters. It helps adjust the total voltage and match the input
requirements of EP500/Pro and AC300 power stations when the solar
panel array’s total open-circuit voltage exceeds the input limit of
EP500/Pro and AC300 (140V/150V).

SAFETY INSTRUCTION
Please check whether D300S is damaged, cracked, liquid leakage, heat or other abnormalities or AC line is damaged before operating. If any, please stop using the product immediately and contact the seller;
Keep a distance of 50mm between D300S and other objects.
Avoid exposing to direct sunlight when the solar system is working and DO NOT place the D300S near heat sources.
It is prohibited to place the equipment in an environment with flammable, explosive gas, or smoke. Since D300S relies on the shell to dissipate heat, over-temperature of the shell will lead to damage.
DO NOT attempt to replace the internal components of the equipment by any unauthorized personnel.
DO NOT operate in wet conditions. Please let the unit dry completely before using if the equipment becomes wet.
Please ensure proper ventilation while in use, inadequate ventilation may cause permanent damage to the equipment.
Do not place anything on the top of D300S, please install it where people cannot touch it.
DO NOT move the unit while operating as vibrations and sudden impacts may lead to poor connections to the hardware inside.
In case of fire, only a dry powder fire extinguisher is suitable for the product.
For safety purposes, please use only the original charger and cables designed for the equipment. We are not liable for damage caused by third-party equipment and may render your warranty invalid.
