Page 13: Installation
FOR WHOLE-SITE BACKUP: Connect the utility grid feed to the “GRID” terminal. • An external service disconnect must be installed between the grid and the Sol-Ark. Size the disconnect according to code. • Connect the “LOAD” output to the Main Service Panel. Follow electric code to select proper wire gauge.
Page 14 National Electrical Code®, paragraph 110.26 and Canadian Electrical Code® CSA C22.1 are adhered to. C. The Sol-Ark 60K-3P-480V is a NEMA 3R - IP65 enclosure that is rated for outdoor installation but can also be installed indoors.
Page 15: Integrating Batteries
Figure 4: Battery Wiring Output Diagram The Sol-Ark inverter has two input battery terminals for single or dual battery connections. To wire a battery to the inverter, lift the actuation levers and insert the 6-4 AWG battery conductor fully into the terminal. DO NOT force open the battery actuation levers more than 90°.
Page 16: Battery Communications
The Sol-Ark 60K-3P-480V inverter can establish closed-loop battery communication through one or two separate RJ-45 ports labeled “BMS1” and “BMS2”. Communication with battery BMS will depend on the wiring of the battery bank and the wiring to the Sol-Ark inverter.
Page 17: Connecting Solar Pv To The Inverter
Configure and wire the HV batteries so that there are two battery banks, each with their separate communication source. Closed-loop communications are established by connecting each communication cable to a BMS port of the Sol-Ark (“BMS1” and “BMS2”). “☐ Parallel Bat1&Bat2” setting on the Batt setup menu SHOULD NOT be enabled, the dual battery bank wiring configuration shown earlier MUST be carried out.
Page 18 AC Coupling on the GRID Side Installing AC coupled inverters upstream of the GRID port of the 60K-3P-480V, such as with a load or supply side connection, is supported for grid connected systems but has some notable limitations when using the inverter for backup or grid-forming mode: Does NOT allow the usage of grid-tied inverter production during grid outages to charge batteries or power loads.
Page 19: Integrating A Generator
Installation of CT sensors on generator lines is only required if “Peak Shaving” is intended to be used. Improve the Generator & Sol-Ark Compatibility Navigate to Settings → Grid Setup → Grid Selection → Grid Mode and program the following values to improve the Sol-Ark and generator compatibility and operating range to avoid frequent disconnections.
Page 20 If connecting more than one HV battery in parallel to the Sol-Ark inverter, divide the Gen or Grid “A” value by the # of batteries to estimate the current (A) flowing to each HV battery.

The CT sensors (or limit sensors) enhance system capabilities by enabling the use of the system work modes known as “Limited Power to Home” (Meter Zero) and “Grid Peak-Shaving”. The CTs will measure and calculate total load demand which the Sol-Ark 60K-3P-480V will then use to accurately supply and offset all existing loads (Meter Zero).

Page 25: Pv Rapid Shutdown
This function REQUIRES batteries to auto detect and auto correct CT orientation. AC coupled inverters need to be OFF during the detection test. If this test is done with connected AC-coupled systems, a factory reset of the Sol-Ark must be performed. Install the CT sensor as described previously.
Page 26 Turn ON battery modules and ensure appropriate voltage on each battery. Verify nominal voltage of battery bank according to the battery installation manual. C. Turn ON the external battery disconnect. Verify that the voltage at the Sol-Ark terminals is within 2% of the voltage measured at the battery bank output.
Page 27: Power Cycle Sequence
TURN OFF all AC breakers / disconnects (“GRID”, “GEN” and “LOAD”). Wait a moment (~1 min) to ensure the inverter is completely de-energized. Make sure that the Sol-Ark is properly connected to the batteries, solar panels, “GRID”, “GEN”, and “LOAD”. Reverse the steps to turn ON the Sol-Ark.

Factory Reset Restrictions: Changes to these settings must be previously authorized by Sol-Ark technical support agents. Parallel Parallel: Enables communications between parallel inverters. “Master” and “Slave” inverters must be programmed.
Page 32 To use the “GEN” terminal as an AC coupling input for micro inverters or string inverters, enable " ! For AC Coupled Input to Gen”. In off-grid systems, the Sol-Ark will use frequency shifting to control the AC coupled solution based on the battery SOC.
Page 33: Limiter
Limiter The Sol-Ark 60K-3P-480V inverter will simultaneously utilize different available power sources to satisfy load demand in the electrical service panels (essential loads panel / main service panel). The following work modes allow the user to determine how power is generated and utilized.
Page 34 “LOAD” terminal (essential loads panel) + excess power to the “GRID” terminal (main service panel AND grid). The Sol-Ark will monitor grid sell and load consumption simultaneously (with +/ - 3% error from CT sensors). The CT sensors MUST be installed.

Page 38 V(Q): Enables the use of Volt-VAr. The Sol-Ark regulates reactive power output to the grid as a function of the voltage to support stabilization during over and under-voltage conditions. V, P & Q: Percentage of nominal grid voltage (V) to which the Sol-Ark will reduce its active power (P) or reactive power (Q). P(Q) / P(F) P(Q): Enables the use of Watt-VAr to regulate reactive power output according to programable active power parameters.
Page 39: Installation Tips
Constant Voltage (CV) Stage When the battery has reached the Constant Voltage setpoint, the Sol-Ark inverter will regulate charging current to maintain the batteries voltage at the CV setpoint, preventing overcharging. The battery is allowed to come to a full state of charge at the CV setpoint. Constant Voltage lasts until the BMS sets the Charge Current Limit to 0A.

CAUTION: Settings below are illustrative, exact values should be confirmed with your respective utility. HECO Grid Compliance Verification for Sol-Ark In cases where HECO compliance requirements are mandated, it is essential to program the following grid parameters in accordance with the HECO specifications.
Page 41: Parallel Inverters
Tech Support for assistance at support@sol-ark.com Parallel systems REQUIRE that each inverter has its own HV battery / battery bank. D. If you do not have batteries on all inverters only parallel the units which have a battery bank.

5.3 Troubleshooting Phase Sequence If the screen of the Sol-Ark inverter shows the error in Fig 35, ensure the phase sequence follows the “Phase Type” programmed under → Grid Setup → Grid Selection. The message “Grid Phase Wrong” is displayed when the inverter does not detect the correct phase sequence.
Page 43 Be sure to check both “GRID” and “LOAD” terminal connections; both must be correct. If the error persists you will need to check your AC connection beyond the inverter and you will need to verify that the phases are correctly labeled from your meter. 0/240/120 0/120/240 Copyright © 2024 Sol-Ark LLC | SK140-0015-003...
