Layout of the EVO-4248SP
Refer to Section 2 of the Owner’s manual to become familiar with all the relevant connection points and components

Mounting the Units

Refer to mounting information at Section 3.3 starting at page 35 of the Owner’s Manual
Plan a safe location and routing of wiring for the associated components
The mounting surface should be able to support a weight of 3 times the weight of the Ninverter for 1 minute.
Ensure that the mounting location is cool, dry and allows unobstructed air flow for cooling
Use 4 pcs of ¼”or M6 mounting bolts and washers. All dimensional information is shown in Fig 3.1 of the Owner’s Manual.

CAUTION!
PLAN SYSTEM GROUND AND GROUND FAULT PROTECTION PRIOR TO INSTALLATION

Ensure that the entire installation is properly grounded to meet Local and National Electrical Codes.
Refer to grounding at Fig 3.12 at page 53 of the Owner’s Manual.
Ensure that the AC Neutral is bonded to the Earth Ground at only one point.

Plan the Battery Bank

Select the type and size of the battery bank and bank configuration. Refer to Section 3.4 of the Owner’s Manual regarding installation of batteries.
Determine the overall Ah capacity (C) of the battery bank.
Check with the battery manufacturer regarding maximum recommended charging current. The factory default “Bulk Current” parameter is set to 20A.
Locate an appropriate area for the battery bank and cable routing to the EVO-4248SP.
The EVO-4248SP comes with a battery temperature sensor model EVO-BCTS. This sensor provides battery temperature information to the charging algorithm to ensure a proper and safe charge to the battery. Refer to Section 2.5 of the Owner’s Manual.
An appropriately sized DC disconnect switch is recommended.

Select and procure the appropriate wire size and lengths for the intended type of installation along with the appropriate breaker/fuse sizes

For sizing the AC input wiring and breakers, refer to Table 3.2 of the Owner’s Manual.
For sizing the AC output wiring and breaker, refer to Table 3.3 of the Owner’s Manual.
For sizing the DC (Battery side) wiring and fuse, refer to Table 3.1 of the Owner’s Manual.

Determine whether the optional EVO-RC-PLUS remote control is necessary for your application

The Optional EVO-RC-PLUS Remote Control provides useful functional information such as battery voltage, battery charging status, and AC output power. EVO-RC-PLUS Remote Control is also capable of logging events to an SD card to create a history record of usage and performance.
EVO-RC-PLUS Remote Control is required to adjust any of the programmable parameters to customize its functionality to your specific requirements. For all programming instructions, please refer to the Owner’s Manual for Remote Control EVO-RC-PLUS.
If the factory defaults are adequate for your requirements or once parameters are adjusted to meet your requirements, it is not necessary to keep the EVO-RC-PLUS attached to the EVO-4248SP Inverter/Charger to maintain functionality.
If the user would like to have the EVO-RC-PLUS Remote Control installed, there is a 1:1 wall cutout template in the EVO-RC-PLUS box for a flush mounted installation with basic installation instructions.
