up to 31 in parallel. When connecting in parallel, the positive poles of the power line are connected in
sequence, and the negative poles are connected in sequence. The communication line is connected from the
“CAN/RS485” of the first battery to the “CAN/RS485” of the second battery, and the “CAN/RS485” of the
second battery is connected to the " CAN/RS485" of the third battery, and so on, can connect up to 31
batteries. The DIP switch on the panel needs to set up DIP configuration address.

--Breaking the product seal (opening the casing)
--Transport damage
--Incorrect installation or commissioning
--Failure to observe the user manual, quick installation instructions
--Incorrect usage or inappropriate operation
--Insufficient ventilation of the device
--Failure to observe the applicable safety regulations
--Force majeure
Neither does it cover cosmetic defects which do not influence the energy production.
Warranty conditions
If the battery becomes defective during the agreed factory warranty period and, unless this should be
impossible or disproportionate, one of the following options will be selected at the discretion of factory:
--Battery repair or
--Battery repair at on-site, or
--Exchange for a replacement device of equivalent value with regard to model and age.
