A properly sized AmpliPHI battery bank based on the maximum charge from the AC Coupled solar PV array
has a minimum of 6 batteries. This helps ensure that the battery bank receives as much charge as possible
from the AC Coupled solar PV.
CAUTION: Using fewer than the calculated number of PHI batteries in this AC Coupled
charge calculation may result in limitedly effective charging from AC coupled PV in Off-Grid
or Grid-Outage conditions.
When the output of the AC Coupled Solar PV array exceeds the MAX A Charge parameter, and frequency shift
is unable to mitigate the output, the battery charging will be interrupted. To avoid this, PV Array sizing needs to
be adjusted to accommodate the MAX A Charge parameter for the overall system.
Homeowners with little to no loads on during the day (while solar power production is at its peak) might
consider sizing a larger AmpliPHI battery bank to take advantage of the entire solar PV output potential for
battery charging. Homeowners that consistently power loads during peak solar power production times may
require a smaller sized battery bank.
4.0 – Installation
4.1 – Installation Options
The AmpliPHI 3.8 Batteries can be mount
ed in practically any orientation (terminals up or on any side), with no
impact to the performance of the AmpliPHI Battery. Do not install them upside down, with the terminals facing
the floor. A maximum of 40 AmpliPHI batteries can be connected together via their communications cables to
an approved inverter.
4.2 – Environmental Considerations
4.2.1 – Charging at Temperatures Below Freezing
The AmpliPHI Battery’s internal BMS and protective circuitry prevent it from charging below 32° F
(0° C) and discharging below -4° F (-20° C), unless connected to an approved inverter. Therefore,
SimpliPhi recommends installing the battery in conditions where ambient temperature does not drop
below freezing in order to maintain AmpliPHI battery system operability.
