1.0 – Important Safety Information

1.1 – Safety Instructions

1. Before using the PHI Batteries, read all instructions and cautionary markings on the PHI Batteries,

and all appropriate sections of this manual.

2. PHI Batteries must be fully charged before commissioning (i.e. before connecting loads). Failure to

do so will void the Warranty.

3. Use of accessories not recommended or sold by the manufacturer may result in a risk of fire, electric

shock, or injury to persons and will void the Warranty.

4. Verify system settings are in compliance with the PHI Battery Warranty and this PHI Battery

Installation Manual (which take precedence). Violating Warranty conditions specified in these

documents will void the Warranty on the PHI Batteries.

5. Consult the Integration Guide for Inverter and Charge Controller programming settings for relevant

warnings and notices. Violating Warranty conditions specified in those Inverter Integration Guides

will void the Warranty on the PHI Batteries, not just the inverter equipment. Consult SimpliPhi Power

Technical Support regarding any inconstancies with other referenced documents.

6. Although each PHI Battery contains an internal BMS with circuitry that protects the PHI Battery cells

from overcharge, over-discharge and extreme load amperage, the PHI Batteries must always be

installed with appropriate inverter and charge controller settings and power electronics to protect the

PHI Battery from open PV voltage and other high voltage charging sources. Do not attempt to

replace existing power electronics without SimpliPhi’s written approval. Failure to adhere to

installation protocol will void the Warranty.

7. Verify polarity at all connections with a standard volt meter before 1) energizing the system and 2) on

batteries with threaded stud connections, before switching the built-in circuit breaker to the “ON”

position. Reverse polarity at the PHI Battery terminals will void the Warranty and destroy the PHI

Batteries.

8. PHI Batteries pose some risk of shock or sparking during the installation and initial wiring and

connection process. This is consistent with all other battery-based storage formats. For batteries with

threaded stud connections, be sure the built-in circuit breaker is in the “OFF” position to minimize the

risk of shock or sparks during the installation and commissioning of the system.

9. To avoid a risk of fire and electric shock, make sure that existing wiring is in good condition and that

wire is not undersized. Do not operate the unit with damaged or substandard wiring.

10. Do not operate if the PHI Battery has been damaged in any way during shipping or otherwise.

11. Only use a SimpliPhi approved LFP battery charger if ancillary charging is required before

installation, testing or troubleshooting. Failure to use a SimpliPhi approved LFP battery charger will

damage the PHI Battery and void the Warranty. See Appendix C for a complete list of approved

chargers.

12. To reduce the chance of short-circuits, always use insulated tools when installing or working with this

equipment.

13. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with

electrical equipment.
