1.3 Safety Precautions
Reminding
1) It is important and necessary to read the user manual carefully before installing or
using battery. Failure to do so or to follow any of the instructions or warnings in
this document can result in electrical shock, serious injury, or death, or can
damage battery, potentially rendering it inoperable, which is out of product
warranty scope.
2) If the battery is stored for long time, it is required to charge them every six months,
charge the SOC to no less than 90%
3) Battery needs to be recharged within 12 hours, after fully discharged.
4) Do not connect power terminal reversely.
5) All the battery power terminals must be disconnected for maintenance.
6) Please contact the supplier within 24 hours if there is something abnormal.
7) Do not use cleaning solvents to clean battery.
8) Do not expose battery to flammable or harsh chemicals or vapors.
9) Do not connect battery with PV solar wiring directly.

10) Any foreign object is prohibited to insert into any part of battery.
11) The warranty claims are excluded for direct or indirect damage due to items above.
1.4 Before Connecting
Warning
1) After unpacking, please check product and packing list first, if product is damaged
or lack of parts, please contact with the local retailer.
2) Before installation, be sure to cut off the grid power and make sure the battery is
in the turned-off mode.
3) Wiring must be correct, do not mistake the positive and negative cables, and
ensure no short circuit with the external device.
4) It is prohibited to connect the battery and AC power directly.
5) The embedded BMS in the battery is designed for 51.2Vdc, please DO NOT connect
battery in series.
6) Battery must connect to ground and the resistance must be less than 0.1Ω
7) Please ensured the electrical parameters of battery system are compatible to
related equipment.
8) Keep the battery away from water and fire.
1.5 In Using
1) If the battery system needs to be moved or repaired, the power must be cut off
and the battery shall be completely shutdown.
2) It is prohibited to connect the battery with different type of battery.
3) It is prohibited to connect batteries with faulty or incompatible inverter.
4) It is prohibited to disassemble the battery.
5) In case of fire, dry powder fire extinguisher or vast amount of water can be used.
6) Please do not open, repair or disassemble the battery except staffs from Pylontech
or authorized by Pylontech. We do not undertake any consequences or related
responsibility which because of violation of safety operation or violating of design,
production and equipment safety standards.

7) DO NOT connect in parallel with US series, UP series and other 48Vdc product from
Pylontech.
