4.5.2 – Making AC Connections AC Landing Points – Terminal Blocks The AccESS is equipped with multiple knockouts on either side of the unit for accessibility to the Sol-Ark’s AC connections. All AC connections are rated at 120/240 VAC. The bi-directional grid port can also support two out of three phases of a 208 VAC grid connection (the two phases being L1 and L2, 120° out of phase).
Generator AC Wiring Generators wired to the Sol-Ark must be rated at 240VAC. Installations outside North America that incorporate generators rated at 230VAC / 50Hz can be wired to the Sol-Ark, provided there is no Neutral wiring connection. Generators can either be wired to the Sol-Ark’s Generator Input Port or to the Sol-Ark’s Bi-directional Grid Port. In grid-connected systems, generators cannot be wired to the Grid Port.
4.5.3 – AC System Bonding Multiple AC Neutral-to-Ground Bonds Verify that only one neutral-to-ground bond exists in the system. Having more than one neutral-to-ground bond in a system violates local electrical codes, may create a shock or fire hazard, and may cause some sensitive equipment to malfunction. The Sol-Ark’s neutral busbar accepts wire sizes up to 4 AWG. Failure to follow these instructions can result in death or serious injury and will void the Warranty.

The charge controller’s maximum short circuit current (I SC) input is 33ADC. Temperature also slightly affects the solar PV module’s current output: current increases as temperature increases.
4.5.5 – Limiter Sensor Wiring Connections The Sol-Ark AccESS installation may include limiter sensors. Limiter sensors are required in the following applications: • Limited to Home mode • Time of Use Selling mode • Systems that include both a generator and grid connection Install limiter sensors on incoming electrical service wires L1 and L2, at the top of the main house breaker panel (refer to Sol-Ark’s diagram on page 11 of the Sol-Ark-8K Manual).
4.5.6 – Basic Functional Test The following procedure should be followed once the installation is complete and before it is put into service. Step 1: Confirm All Connections After the AC and DC wiring has been installed and connected, check that all connections are correct and secure. Step 2: Apply Battery Power to the Inverter 1. Measure the voltage and check polarity at all battery connection points.
Step 5: Fully Charge the Battery Bank Prior to Powering On Loads A connection to an AC power source will result in the Sol-Ark automatically charging the batteries from that power source when the Sol-Ark is turned ON. If the system does not include any AC power source, and only solar PV as the batteries’ charging source, turn on the PV disconnect and wait until the PHI battery bank has had a chance to charge fully via solar power before turning on any loads.
5.0 – Programming 5.1 – Depth of Discharge The AccESS Sol-Ark comes pre-programmed for a maximum 80% depth of discharge (DoD) on the PHI batteries. This qualifies the batteries for the 10-year / 10,000 cycle Warranty. To change the batteries’ DoD to the 5,000-cycle Warranty or 3,500-cycle Warranty, modify the State of Charge (SoC) percentages as outlined in this Operating Parameters section of this Manual.

This value represents the minimum power required of the solar array before the Smart Loads are powered.
Grid Setup Settings The Sol-Ark’s Grid Setup menu includes many advanced features (refer to Section 5 of this Guide). Regardless of the features used, the PHI battery bank should never discharge more than its maximum continuous discharge rate. Furthermore, to maintain the PHI batteries’ Warranty at a 10,000-cycle level, also do not discharge the battery bank to a State of Charge (SoC) level less than 20%. These details are controlled in the Grid Setup menu’s Limiter tab. Figure 21.

Time of Use Selling / Energy Arbitrage Discharge batteries to power circuits during specific set times. Program these times to coincide with the utility company’s peak pricing times to avoid high energy charges from the utility.
Off-Grid The Sol-Ark automatically operates in Off-Grid mode when it does not detect a grid connection. In an Off-Grid system setup, all the home’s loads are connected to the Sol-Ark’s Load Output (50A doublepole breaker). Do not use the Sol-Ark’s Grid Sell and Limited to Home modes in an off-grid system setup. Check the Limited power to load box in the Limiter tab of the Sol-Ark’s Grid Setup / Grid Param menu to allow for the batteries’ power to discharge to the connected loads.
In an AC Coupled system setup that includes a generator, using a transfer switch for a grid-or-generator connection to the Sol-Ark’s Grid Input also frees up the Sol-Ark Generator Input for connection to the AC Coupled solar PV array. If the system includes both a generator and a grid connection, limiter sensors are required.
