Wiring Connections
Before starting any wiring, prepare cables and circuit breakers that meet the specified requirements. The cable AWG and circuit breaker specifications are determined by the maximum current the cable needs to bear. Refer to the instruction manual for detailed matching wire AWG and circuit breaker specifications.
- Battery Connection: Use 2AWG wires for connecting the battery. Ensure positive terminals are matched with positive and negative with negative.
- AC Input/Output: Use 10AWG wires for AC input and output. For AC input, ensure a grounding connection is made.
- PV Input: Use 12AWG wires for PV input.
- Grounding: Properly ground the inverter using an 11AWG wire connected to the grounding port on the unit. Keep the grounding point as close as possible to the inverter for maximum effectiveness.

4. Operating Modes and Settings
The PowMr POW-SunSmart 6.5KP-1 offers flexible operating modes to optimize energy usage based on your specific needs. These modes can be configured via the LCD display.
Output Source Priority Modes
These settings determine the sequence in which the inverter allocates solar energy, grid power, and battery power to the load.
- AC1ST (Grid Priority Mode): Grid power takes the highest priority. If grid power is unavailable, the system switches to solar power and battery power. Suitable for areas with unstable grid power, serving as a backup UPS.
- BT1ST (Inverter Output Mode): Prioritizes the use of battery and solar power to supply the load. If solar energy is insufficient or unavailable, the system switches to grid power. Suitable for regions with stable grid power supply.
- PV1ST (Solar Priority Mode): Solar power and battery power take precedence. If solar energy is insufficient or unavailable, the inverter switches to bypass mode to supply the load from the grid. This mode aims to maximize solar energy utilization.

Charging Source Priority Modes
These modes define the order in which the inverter charges the battery with solar energy and grid power.
- Hybrid Priority: Inverter prioritizes charging the battery with solar energy. If solar power is insufficient, grid power is used simultaneously. Suitable for regions with unstable solar energy supply.
- AC1ST (Grid Power Priority): Grid power takes precedence for battery charging. If grid power is absent, the inverter switches to solar power for battery charging. Suitable for areas with relatively unstable grid power supply.
- PV1ST (Solar Priority): Prioritizes using solar power for battery charging. If solar energy is unavailable, grid power is utilized. Better suited for regions with stable grid power and high electricity rates.
- ONLYPV (Solar Power Charging Only): Exclusively relies on solar power to charge the battery, regardless of grid power availability. Ideal for regions with abundant daylight hours.

Time-of-Use Charging and Discharging Strategy
The inverter offers flexibility to set specific time periods for battery charging and discharging. This allows you to align your energy usage with local electricity consumption patterns and pricing policies, ensuring efficient utilization of your battery resources.
- Charging Periods: Three configurable charging periods (Settings 40-45).
- Discharging Periods: Three configurable discharging periods (Settings 47-52).
