2.3 – Eliminating Battery Temperature Compensation
The PHI Batteries’ charging regimen does not include any temperature compensation. To achieve this, remove
the Remote Temperature Sensor (RTS) from the system entirely.
3.0 – PHI Battery Bank Sizing
PHI Batteries are designed to operate at the continuous ratings listed on the relevant PHI Battery model’s
Specification Sheet. Therefore, a properly sized PHI Battery bank must be sized to handle both the inverter’s
“load rate” as well as the maximum potential charge rate from the solar photovoltaic (PV) array. Take care to
consider not only the energy (kWh) requirement of the battery bank, but also all other power-related sizing
parameters, as outlined in Sections 3.1, 3.2 or 3.3 and 3.4. Failure to do so will Void the Warranty.
CAUTION: PHI Battery bank sizing not in accordance with the following sections will damage
the PHI batteries and Void the Warranty
3.1 – Sizing for Maximum Instantaneous Discharge (Load Rate)
The load rate is the amount of power that is discharged from the battery bank to the loads. This may include both
alternating current (AC) and/or direct current (DC) loads. PHI Battery banks are sized so that the batteries’
combined maximum continuous discharge rate meets or exceeds the load rate.

Because most loads are AC loads, the load rate is typically represented by the inverter’s AC Power Output rating.
Convert the inverter’s maximum potential AC power draw to the maximum potential DC power draw from the
battery bank by factoring in the inverter’s efficiency rating.

Example: An inverter rated at 5 kW AC and 92% efficiency potentially draws 5.4 kW DC from the battery bank.
