The product should be placed in a well-ventilated place. Do
not place the product in a sealed or air-tight position or
cabinet, otherwise it will affect the operation performance
and system life of the energy storage system.
Avoid direct sunlight. Do not place this product near stoves
and fire sources. Otherwise, the lithium battery in the
product system will leak or even explode.
The maintenance personnel of this product must
understand the knowledge and skills related to inverter
and battery maintenance.
ESI Series products are transformerless inverter which
requires the positive pole and negative pole of the PV array
are NOT grounded. Otherwise, it will cause inverter failure.
In the PV system, all non-current-carrying metal parts (such
as mounting frame, combiner box enclosure, etc.) should
be connected to earthed.
Reminder: Do not disassemble and destroy the battery. The
toxic electrolyte in the battery can damage your skin and
eyes.
Caution: Comply with the following requirements during the
installation and maintenance of the product:
A) Remove watches, rings and other metal objects from your
body.
B) Use tools with insulated handles.
C) Wear rubber gloves and shoes.
D) Do not place tools or metal objects on the battery.
