BASCO Integration Guide
A maximum of 6 stacks can be connected in a single system.
Per NFPA 855, a maximum of 40kWh in utility spaces or  basements and 80kWh in garages our outdoor locations.
Systems larger than 80kwh should consult local AHJ for site requirements.

Required Tools

Materials Not Included
Floor Mount and Base Mount are ordered separately and fasteners are not included.

Floor mount base not intended for seismic zones.

Do not install the Battery Temperature Sensor. The PHI Batteries require no temperature compensation.

Provided Components
Each stack must have a Briggs & Stratton controller at the top and a Briggs & Stratton floor or wall mount bracket base on the bottom. Each stack must be installed at least 3 feet away from each other.

Structural Attachment Required
The installed wall hardware must be attached to concrete or finished studs. Drywall anchors can be used in addition to, but cannot replace, the structural hardware. 
Don’t let your stationary battery system accidentally become a mobile battery system!

Alert
Reserve Capacity of 20%
To optimize the PHI batteries’ and overall system’s performance and life, SimpliPhi Power recommends programming the equipment settings for an 80% maximum Depth of Discharge (DoD). Maintaining the PHI battery at this DoD qualifies it for the 10-year / 10,000 cycle Warranty level. SimpliPhi warranties the PHI battery for fewer cycles at greater DoD levels: 90% DoD is correlated with a 5,000-cycle Warranty and 100%
DoD correlates with a 3,500-cycle Warranty. 

Installation Angle
The SimpliPHI 6.6 battery is designed to be vertically mounted. The battery system must be installed upright with
less than 1° tilt from vertical. 

Do not install the battery system upside down, on its back, side, more than 1° tilt from vertical, or on tilted walls. When installing the SimpliPHI 6.6 battery on uneven or sloped surfaces, it might be necessary to install shims between the floor and the bottom of the foot.

Floor Mount Base Installation

(ordered separately)

For non-seismic zone floor mount installations, install on
concrete floors with anchors using 1/4"-5/16” fasteners to >2” deep or wood floors with 1/4"-5/16” lag screws to full thread engagement through the subfloor.

Use a level to determine if the floor is level and that the wall is plumb. If the floor is not level, shims can be used to create a level surface.

Use a measuring tape to determine the hole positions for the floor mount base according to Figure 2 below. Mark the positions using a marker or pencil.

NOTE: Use the provided positioning guide to determine spacing from the wall to the floor mount base. The back holes of the floor mount base must be ~1⅝” from the wall, not
including the baseboards.

External Charger
Only use a Briggs & Stratton approved LFP charger if ancillary charging is required at any point before or during installation, testing or troubleshooting. Failure to use a Briggs & Stratton approved LFP charger will damage the SimpliPHI Batteries and violate the terms of the Warranty.

Single Stack Wiring
When connecting a single stack to a single charge controlling device with a built-in disconnect for the batteries, no external disconnect is necessary. If there is not a disconnect built-in to the charge controlling device, a disconnect must be installed between the battery stack and charge controlling device. 

This disconnect must be sized to the device with the lower rated current. If the disconnect sizing requirements are uncertain, refer to local AHJ and NEC guidelines. When connecting a single stack to multiple devices, a disconnect is required between the battery stack and the charge controlling devices.

Recommended OCPD
Remember each battery port on the Sol-Ark 15K is rated for 200A. To get a full 275A out of the Sol-Ark 15K, use both battery ports and ensure cable run is suitably rated for full amperage. 
Parallel Stack Installation
Up to 6 SimpliPHI 6.6 Battery Stacks can be wired in parallel from the terminals of the Controller to a properly sized combining busbar. Between each stack and the busbar, a DC single-pole overcurrent protection device is required (double-pole is recommended). 

Follow local AHJ and NEC DC overcurrent protection device sizing requirements. The table above lists the recommended overcurrent protection device size per NEC 2023. 

Make sure that all cable lengths from each stack are identical in length and gauge to maintain equal resistance across the stacks.


Alert
Caution
Identical wire lengths and identical wire gauges from each SimpliPHI Battery in a SimpliPHI Battery System is a critical feature of parallel power storage systems that must be adhered to. Failure to properly wire the SimpliPHI Batteries in parallel can damage the system and will violate the terms of the Warranty

Electrical Wiring Instructions
Turn ON the SimpliPHI 6.6 BESS (hold power button on the Controller until all LEDs on batteries and Controller are ON.)

2. Measure the voltage at the Controller power terminals. 

NOTE: If the SimpliPHI Battery’s voltage has dropped to a voltage below the inverter’s minimum starting voltage requirement, then the battery will need to be charged using an external charger. SimpliPHI batteries have a very low self-discharge rate and typically do not require ancillary charging,but an extended period in storage can cause the batteries to
discharge.

Electrical Wiring Instructions Pt 2
3. Turn OFF the SimpliPHI 6.6 BESS. (Hold the power button on the Controller until the Controller LEDs are OFF.)

4.Measure the voltage at the Controller power terminals. The voltage will measure <5 VDC if the system is off.

Ground Cable Installation
A grounding position is provided to comply with local AHJ and NEC grounding requirements. Ground as required. 

Terminate the ground cable (sized to local AHJ and NEC requirements) with a 1/4” closed-end Ring Terminal.

Cover the exposed wire between the lug and wire sheath with heat shrink.

Attach the ground wire with the ¼” ring terminal with the M5x10mm screw provided, as shown in Figure 26.

Torque to 1.7 ft-lb maximum (20 in-lb)

Power Cable Installation
Terminate the Negative and Positive cables (sized to local AHJ and NEC requirements) with a ⅜” closed-end Ring Terminal. Cover the exposed wire between the lug and wire sheath with heat shrink.

Do not use power tools or impact drivers to tighten the terminal hardware. This can result in damage to the terminal and will violate the terms of the Warranty.
