VertaMax User Manual

Revision 1.0

2.1 ELECTROSTATIC (ESD) PRECAUTIONS

All electronic circuits may be damaged by static electricity. To minimize the likelihood of electrostatic

damage, discharge yourself by touching an electrical ground (e.g.: copper pipe) prior to handling the unit and

avoid touching components on the circuit boards. The risk of electrostatic damage is highest when relative

humidity is below 40%.

2.2 MOUNTING

Mounting is optional for the VertaMax; however, the environment must be dry and protected from water.

1. The VertaMax can be mounted on a vertical or horizontal surface. If mounted vertically, the unit

should be oriented such that neither end is at the top so foreign material cannot settle into the

unit.

2. Install four user-supplied fasteners through the four inverter mounting slots and into the

mounting surface.

3. Tighten all the fasteners to ensure the inverter cannot slide in any direction.

WARNING: Do not mount on flammable surface material.

2.3 GROUNDING

The VertaMax is designed to work with grounded electrical systems. In the inverter, ground is not connected

to the input terminals.

Use a copper wire to connect the grounding terminal on the VertaMax enclosure to earth ground or chassis

ground. The grounding terminal is located on the AC Output end of the inverter.

Do not connect the system negative conductor to this terminal. NEC requires the use of an external ground

fault protection device (GFPD). The system electrical negative should be bonded through a GFPD to earth

ground at one (and only one) location. The grounding point may be located in the solar/wind circuit or the

battery circuit.

2.4 CONNECTIONS

WARNING: Electrical installations must meet local and national wiring codes, and should be performed by a

qualified electrician.

WARNING: Do not connect the inverter and another AC source (such as a generator or utility power) to the

AC wiring at the same time.

WARNING: Do not connect the inverter to an AC branch circuit that has high-power consumption loads. It

will not operate electrical appliances that consume more than the units rated watts.

WARNING: Loose connectors result in excessive voltage drop and may cause over heated wires and melted

insulation, which can lead to electrical fires.

WARNING: Reverse polarity connections (positive to negative) will blow internal fuses in the inverter and

may permanently damage the Inverter.

IMPORTANT: The NEC requires that the wires carrying the system current never exceed 80% of the

conductor’s current rating (sizing recommendations are located in Section 4).

IMPORTANT: In addition to the protection provided by the Inverter’s internal fuses, NEC requires a UL-listed

fuse in the battery’s positive DC cable as close to the battery as possible (sizing recommendations are

located in Section 4).

1) The VertaMax has four DC terminals (two positive and two negative) to share the load. Both positive

terminals are internally bonded and both negative terminals are also internally bonded. The four cables

used for these terminals should be of equal length.
