SimpliPhi Warranty

| 4 |

CAUTION: Circuit Breakers, Disconnects and Fuses should be employed throughout several points of a

Power storage and generation installation to effectively isolate and protect all components of the system

to safeguard against faults, short circuits, polarity reversals or a failure of any component in the overall

system. Fuses, breakers, wire ratings and values should be determined by established standards and

evaluated by certified electricians, licensed installers, and regional code authorities. Although each PHI Battery

contains both an 80 Amp circuit breaker and an internal BMS with circuitry that protects the Lithium Ferrous

Phosphate cells from overcharge, over-discharge and excessive load amperage, the PHI Batteries must

always be installed with a charge controller and the appropriate voltage settings to protect the PHI from open

PV voltage and other high voltage charging sources. The PHI Battery Management System (BMS) and

internal circuit breaker alone will not protect the PHI batteries from these extreme electrical phenomena.

Failure to adhere to installation protocol will void the Warranty. To obtain maximum lifetime capacity (cycle life),

a properly sized bank will operate at an average maximum output not to exceed C/2 (refer to other limitations

as identified herein for each model). Ensure the size of the bank is greater than twice the kW potential load.

Inverter/charger size shall follow a 1:2 ratio.

CAUTION: All PHI batteries must be fully charged before commissioning the system (i.e. before connecting

loads). Failure to do so will void the Warranty.

CAUTION: Verify polarity at all connections with a standard volt meter before:

1.) Energizing the system and

2.) In the case of PHI 3.8 and PHI 2.9 models, before switching the breaker to the “ON” position.

Reverse polarity at the battery terminals will void the Warranty and destroy the batteries.

CAUTION:

Only use a SimpliPhi approved LFP charger if ancillary charging is required before installation,

testing or troubleshooting. Failure to use a SimpliPhi approved LFP charger will damage the battery and

void the Warranty.

CAUTION: Charging LFP batteries at temperatures below freezing. Do not attempt to charge the

battery below 32° F (0° C). Attempts to charge at subfreezing temperatures can adversely affect SOH and

cycle life, and will void the Warranty.

If the battery must be charged below 32° F (0° C), the rate of charge must be at no more than 5% of the

battery’s rated capacity (C/20).

Section 2.0 – SimpliPhi Power Guide for Operating

Parameters

Although SimpliPhi batteries are capable of performing at very high rates and depths of discharge within a

very wide temperature range, in order to achieve extended life cycles and to comply with the Warranty,

follow all inverter and charge controller programming guidelines outlined in the relevant SimpliPhi

Installation Manual and Integration Guide(s). These documents can be found on SimpliPhi’s Product
