AmpliPHI Sol-Ark Integration Guide

A properly sized AmpliPHI battery bank based on the maximum draw of the critical loads sub-panel has a

minimum of 4 batteries, even in this Grid-Tied with Battery Backup application. Note also that during a grid

failure, the critical loads’ maximum energy draw (kWh) is also limited by the battery bank’s capacity.

5.3 – Limited to Home

Checking the Limited power to Home box in the Limiter tab of the Sol-Ark’s Grid Setup / Grid Param menu

allows for all loads* (on both the critical loads sub-panel and the main house breaker panel) to be powered using

the connected solar PV and/or batteries. The Sol-Ark prioritizes powering these loads from solar PV first (if

available), then (2) grid, (3) generator, and (4) batteries. To prioritize the batteries’ use over the grid or

generator during specific set times, also use the Time of Use Selling mode.

*While the Limited to Home mode allows for all loads to be powered using solar PV and/or batteries, the Sol-

Ark prioritizes powering loads on the critical loads sub-panel first, and loads on the main house breaker panel

are offset by solar (and/or batteries, during Time of Use Selling mode times) as much as possible. If the loads’

draw exceeds the available power from the solar PV array and (with Time of Use Selling mode also in play) the

batteries have also discharged to their minimum programmed SoC percentage level, the Sol-Ark will then

resort to powering loads using grid power.

CAUTION: IN LIMITED TO HOME MODE, LIMITER SENSORS ARE REQUIRED TO

ENSURE THAT THE HOME’S MAIN BREAKER PANEL CIRCUITS ARE POWERED

WITHOUT EXPORTING ENERGY TO THE GRID.

5.4 – Limited to Load

Checking the Limited power to load box in the Limiter tab of the Sol-Ark’s Grid Setup / Grid Param menu

discharges the battery to power the critical loads sub-panel’s loads. The Limited to Load mode does not allow

for any solar or battery energy to power the main house breaker panel and it does not allow for any solar or

battery energy to be exported to the grid.
