The NEW REVOLUTIONARY AIMS Power Hybrid Inverter gives you total control of your power. It combines solar power and battery backup into one complete, easy to use solution, that utilizes the FREE power from the sun and independence from the grid. In addition, the AIMS Power Hybrid Inverter can reduce or eliminate electric bills, provides power during outages, and allows customers to monitor their system from anywhere. Where the AIMS Power Hybrid Inverter makes an immediate impact is in its ability to be programmed to do exactly what you want it to do. Think of an orchestra without a conductor. It may have all the talent and potential in the world, but without a way to organize and direct it, you may as well listen to radio static. The AIMS Power Hybrid Inverter is essentially the conductor for every source of power that you have in your house. Instead of sending the suns power straight to the power company where they dictate the rate, you can decide how to use YOUR power. On a sunny day, you can program it to fill up your batteries first, and then power your house. If you are not home, you can pump the excess power back to the Utility Co. and offset your power bill. Have an EV car? When you get home, you can charge from batteries or use FREE solar power. You can program it to power your house at night with batteries and recharge during the day with sunlight. Did the grid go down? In the blink of an eye, it automatically switches over to batteries. Sun not shining? You can charge your batteries using the grid when rates are low and power your house at specified times. Have a generator? Use it to charge your batteries instead of using the grid or solar. AIMS Power Hybrid Inverter gives you complete control and autonomy over your own power needs because that is exactly what homeowners deserve. The hybrid inverter also includes an APP for remote monitoring which is easy to set up and operate using your cell phone. No matter where you are, you will have the ability to do exactly as you see fit with your power. While there may be other similar products on the market, our hybrid inverters are much more efficient than the competition because of the higher voltage that they run at. This puts less stress on the entire system and ensures extended durability and improved safety, which is something that we pride ourselves in providing for our customers. In addition to being more durable, efficient, and safe than others on the market, all of the easy to use optional kits that are designed for the AIMS Power Hybrid Inverter are from the same manufacturer. This means that instead of having to call three different customer service lines to troubleshoot issues, you will be able to avoid the runaround and work through them with one trusted and competent company. We believe that taking the headache out of troubleshooting is what our customers deserve, and that is what separates us from the competition.

The AIMS Power hybrid inverter charger is designed to provide grid-tie and off-grid solar power management in one product. Its simple but comprehensive design eliminates the need for extra equipment, providing an efficient solution for users interested in off-grid battery backup, net metering, and load sharing all in one product. Energy management is based on time-of-use and demand charge rate structures, significantly reducing the amount of energy purchased from the public grid and optimized self-consumption. Backed by a 10 year warranty and lifetime tech support. This inverter is designed to work with solar panels and/or a battery bank and is interactive with the grid. You don't need both solar and batteries. Main LCD Home Screen

EPS Emergency Power Supply (critical load) The EPS section allows you to view and change the EPS parameters. Tap the EPS icon on the home main screen to view. Load The load screen provides info regarding the load and consumption.

The Settings section allows you to access all settings and modes within the inverter. Detailed info later in the manual. General Mode Overview From the main screen, click on the settings icon in the bottom right corner. Click on Mode Set. There are four General Modes. To access each mode, click in the highlighted field and select the mode you want to set. See page 31 for setting instructions.

The Self Use mode is for regions with low feed-in tariff and high electricity prices. The energy produced by the PV solar system is used to optimize self-consumption needs. The excess energy is used to recharge the batteries and any remaining energy is then exported to the grid. Most commonly used. Selling Fir st The Selling First mode is used when using solar is main priority. The panels will power the loads first and any excess energy will go back to the grid if PV is producing more than the load.

Charge First mode is aimed at the areas of instability of electrical energy. The panels will charge the battery bank first and any excess energy will then power the electrical loads. The remaining energy will go back to the grid. This setting will also allow you to use solar and grid to recharge the batteries if the solar panels can’t produce enough power to charge the batteries. Command Charge This mode will allow you to force charge the battery using the grid first. The command charge will charge the battery when the voltage is low, or the user can change the charge time to a time when the grid rates are lower. If the grid is not available, the battery can only be charged by the PV array (if not using a generator). Some users will use this mode if the battery was over discharged.

GENERAL NOTE: No Grid Power Depending on the General Mode you have set for your system, PV and battery will supply the loads. If the solar panels produce excess power, the system will power the load and charge the battery bank. The back up loads will be powered by both the PV and battery bank.

The PIHY series hybrid inverters allow up to three PV MPPT inputs (strings of solar panels). Ensure the following requirements are met before connecting PV panels and strings to the inverter.

• Turn off and open all of the PV (DC) switches before wiring
• The open-circuit voltage and short-circuit current of the PV string should not exceed the specifications of your inverter
• The isolation resistance between PV string and ground should exceed 300 kΩ
• Ensure the polarity of PV strings is correct
• AIMS Power recommends using the DC plugs included with your inverter purchase. 43" Step 1 PV cable 11±0.5mm
• PV input wire ≥10 AWG, stripping length 11±0.5mm (.43"), and the stripped PV input wire should be tightly crimped into the connectors. PV wire gauge needs to be sufficient to carry maximum current generated by your solar system.
• Pass the PV input wire with crimped terminals through the waterproof connector and follow the system connection diagram as shown above. Insert the black wire PV1-, PV2-, PV3- and the red wire PV1+, PV2+, PV3+ into the terminals on the PCB, and tighten the screws. NOT ALL SYSTEMS WILL HAVE 3 PV INPUTS. Warning: Fatal high voltage may be present on the PV string. Please comply with electric s afety guidelines on page 3 when performing all connections. Please make sure the polarity is correct from the PV strings to the inverter. Otherwise, damage may occur and VOID the warranty. Note: Cable recommendation: Cross-section 10-12AWG Step 2

The hybrid inverter is compatible with lead (AGM, Gel, Open) and lithium batteries. If using lithium batteries, th e PIHY series hybrid inverters are compatible with AIMS Power lithium batteries only (Part #s: LFP230V96A-M & LFP230V96A-S). If you prefer to use a different lithium battery you MUST contact AIMS Power tech support to check compatibility and charging programming. No exceptions. AIMS Power assumes no liability if damage occurs. If using lead, you will need to enter the battery parameters for the batteries you are using on the LCD screen during set up. Note: To set battery type and manufacturer, refer to page 27 (Setting up Inverter). BMS (Battery Management System) communication is needed between inverter and all lithium batteries. Battery type, voltage and capacity must be set prior to use. 4 AWG wire is recommended. AC Connection There are three AC terminals marked with "GRID", "EPS" and "GEN". Before connecting to the inverter, a separate AC breaker between the inverter and AC input power is necessary. This will ensure the inverter is disconnected during maintenance and fully protected from AC input current. An extra AC breaker is needed for On -Grid connection t o be isolated from the grid when necessary. Below are requirements for the On-Grid AC-breaker Grid Connection • Connect DC fuse or breaker before connecting.

• Remove insulation sleeve 11mm (0.43") length, unscrew the bolts, and insert the AC input wires according to proper polarities indicated on the terminal. Block and tighten the terminal screws. Cable recommendation: Cross-section 8-10 AWG Note: A qualified electrician is required for the wiring. Wire size must always exceed maximum current flow that is possible going through the system. Step 1 mm 11±0.5 AC cable Note: .43 Step 2 Warning Make sure that all AC power sources are off before connecting. GRID

Emergency Power Supply Connection (EPS) or Back-Up If installing in a off grid application the EPS will run to main breaker panel with no Grid or Utility power supplied. When running on battery backup and solar during a Grid/Utility power outage, only the EPS will supply AC to loads and should be connected to sub panel. 11±0.5 mm AC cable Note: Cable recommendation: Cross-section 8-10 AWG .43 Generator Connection 11±0.5 mm AC cable Note: Cable recommendation: Cross-section 8-10 AWG Make sure to check polarity and that c onnections are secure and tight. .43 The hybrid inverter has two generator wire options: K1 = Auto Gen Start (no grid) . The generator must have a 2 wire open close feature. K2 = Manual The inverter will provide 4.6kw or 9.6kw (depending on model), to the EPS. The recommended generator size should be 1.5 times of the inverter size to support inverting and charging. An example, if using our 4600 watt inverter, the generator should be @7000 watts. Insert stripped AC output wires into the terminal block according to the proper polarities and tighten the terminal. Corresponding Neutral (N) wires and Protective Earth (PE) wires to the AC terminal should be inserted as well.

A second protective earth (PE) terminal should be connected to the inverter. This prevents electric shock if the original protective PE wire fails. Attach the grounding screw to the grounding connection of the inverter's housing. Note: Make sure the earth cables on the inverter and solar panel frame are separated.
