Installation; Attentions; Requirements For The Pv Array - Epever Tracer-AN Series User Manual

2 Installation

2.1 Attentions

 Be very careful when installing the batteries. Please wear eye protection when installing
the open-type lead-acid battery and rinse with clean water in time for battery acid
contact.
 Keep the battery away from any metal objects, which may cause a battery short circuit.
 Acid gas may be generated when the battery is charged. Ensure that the surrounding
environment is well ventilated.
 Avoid direct sunlight and rain infiltration when installing it outdoor.
 Loose power connections and corroded wires may result in high heat that can melt wire
insulation, burn surrounding materials, or even cause a fire. Ensure tight connections
and secure cables with clamps to prevent them from swaying while moving the inverter.
 Only charge the lead-acid and lithium-ion batteries within the control range of this
controller.
 The battery connector may be wired to another battery or a bank of batteries. The
following instructions refer to a singular battery. Still, it is implied that the battery
connection can be made to either one battery or a group of batteries in a battery bank.
 Select the system cables according to 5A/mm

2.2 Requirements for the PV array

(1) Serial connection (string) of PV modules
As the core component of the solar system, the controller needs to suit various PV modules
and maximize solar energy conversion into electricity. According to the open-circuit voltage
(VOC) and the maximum power point voltage (VMPP) of the MPPT controller, the serial
connection of PV modules suitable for different controllers can be calculated. The below
table is for reference only.
