Installation; Mounting - Offgridtec Smart-Pro Series Manual

2.1 Installation

Visual control:
After receiving your Smart-Pro battery, check it for external damage, e.g. from transport.
Make sure that the polarity is correct when connecting the battery. Connect your positive cables to the positive pole
and your negative cables to the negative pole of the Smart-Pro. Our Smart-Pro series also supports parallel or series
connection (configurations up to 48V systems). The connection terminals have an M8 hole, so most standard
connections work well with our batteries.
Parallel connection:
Multiple Smart-Pros can be mounted in parallel to increase the current capacity of the system. When batteries are
mounted in parallel, the voltage does not change, but the current doubles.
Example: two 12.8V 100Ah Smart-Pros together give a capacity of 200Ah at a system voltage of 12.8V. The
continuous discharge current can be increased to 200A. The peak discharge current remains limited to 500A.
Series connection:
Two identical Smart-Pro batteries can be connected in series to increase the system voltage up to 24V. When the
batteries are connected in series, the current capacities and discharge current remain the same, but the system
voltage is additive. Setting charge voltage of 28.8V and a float voltage below 27.2V.
Example: two 12.8V 100Ah Smart-Pros together give a capacity of 100Ah at a system voltage of 25.6V. Nothing
changes at the current output or input..

2.2 Mounting

The Smart-Pro series can be installed standing upright or lying down.
Make sure that the mounting is sufficient and solid! Avoid direct sunlight!
