All SimpliPHI systems must incorporate either an Essential Loads sub-panel or a transfer switch kit. In the case
of off-grid systems, all the home's loads are on the Essential Loads panel, thereby making the Essential Loads
panel the main house breaker panel. Any distance is permissible between the SimpliPHI system and the
Essential Loads panel or transfer switch kit, provided wire sizing and voltage drop is calculated and in
accordance with local codes.
Prior to the SimpliPHI system installation, determine which of the home's circuits will be located either on the
Essential Loads panel or transfer switch kit. Consider the following:
•
A 50A double-pole breaker or OCPD is required to be installed within the essential load panel for the
SimpliPHI inverter to be wired to.
1. When grid-connected, the maximum continuous power the SimpliPHI Inverter can deliver to
the Essential Loads panel is 25A at 240VAC (6 kWAC).
2. When off-grid, the maximum power the SimpliPHI can deliver to the Essential Loads panel
(also considered the main house breaker panel in an off-grid application) is 25A continuous at
240VAC (6 kWAC) and 50A peak at 240VAC (12 kWAC) for 100 milliseconds.
4.5 – Conduit Installation
Before making any wire connections install conduit on all input, output, solar and battery terminals. Conduit is
not supplied with the inverter.
•
The conduits, hubs and fittings must be rated for outdoor installation and meet code requirements per
your AHJ.
•
All hubs and fittings must comply with UL514B
NOTE: Clamps and fasteners for the attachment of conduit, electrical metallic tubing, armored cable,
nonmetallic flexible tubing, nonmetallic-sheathed cable, service cable, or equivalent that are supplied as part of
an enclosure must comply with the standard for Conduit, Tubing, and Cable Fittings, UL 514B.
STEP 1: Prepare one conduit pipe and two knockouts for each terminal.

Battery Terminals
STEP 2: Install conduit pipe with two knockouts on the Grid/Utility terminal as shown below
STEP 3: Repeat STEP 2 for other connections: generator, solar input and battery terminals separately.
