Mpp Solar PIP-HS User Manual

The Mpp Solar PIP-HS is a high-performance hybrid solar inverter designed for off-grid and backup power applications. It integrates MPPT solar charging, AC utility/generator input, and pure sine wave AC output. Key features include LCD display for system monitoring, configurable charging parameters, multiple operation modes (solar priority, utility priority, SBU), battery equalization, and comprehensive protection features. Below are key sections for safety, features, installation, setup, operation, and troubleshooting.

Features at a Glance

Key components: Pure sine wave inverter, MPPT solar charge controller, LCD display panel, AC input/output terminals, PV input terminals, Battery terminals, Communication ports.

Installation

Unpack and inspect contents. Install in a dry, well-ventilated location.

1. Mount the inverter: Use appropriate wall mounting hardware, ensuring adequate clearance for ventilation.
2. Connect batteries: Connect battery cables to correct polarity terminals (positive to positive, negative to negative).
3. Connect solar panels: Connect PV cables to PV input terminals, observing voltage limits.
4. Connect AC input: Connect utility/generator power to AC input terminals.
5. Connect AC output: Connect load wiring to AC output terminals.
6. Connect communication cables: Optional USB/RS232 for monitoring.

WARNING! High voltage present. Installation should be performed by a qualified electrician. Ensure all connections are secure and properly rated.

First-Time Setup

Power on the inverter; configure basic settings via LCD display.

1. Set battery type: Navigate to menu to select battery type (Flooded, AGM, Gel, User-defined).
2. Configure charging parameters: Set bulk/float/equalization voltages and charging current limits.
3. Select operation mode: Choose SBU, Solar First, or Utility First based on application.
4. Set output voltage/frequency: Configure for local standards (e.g., 120V/60Hz or 230V/50Hz).
5. Enable/disable features: Configure battery equalization, alarm settings, and power saving mode.

CAUTION! Verify all wiring before applying power. Incorrect settings may damage batteries or connected equipment.

System Management: Equalization settings, alarm configuration, system reset. 4. Information: Firmware version, runtime statistics, error history.

Connecting Devices

Battery: Direct connection to battery terminals. Solar: PV input terminals. AC: Input/output terminals.

1. Turn off all power sources before making connections.
2. Use appropriately sized cables for each connection (refer to manual for specifications).
3. Connect batteries first, then solar panels, then AC connections.
4. Install DC and AC circuit breakers as required by local electrical codes.

Tip: Use torque wrench to ensure terminal connections are properly tightened to specified values.

Operation Modes

Three primary operation modes available:

1. SBU Mode (Solar/Battery/Utility): Priority to solar power, then battery, then utility.
2. Solar First Mode: Uses solar when available, switches to utility when solar insufficient.
3. Utility First Mode: Uses utility power primarily, solar charges battery.
4. Battery Mode: Operates from battery only (when AC input is disconnected).
5. Bypass Mode: Directly passes utility power to loads (when inverter is off or in standby).

WARNING! Do not switch modes while under heavy load. Ensure battery has adequate charge when operating in battery-only modes.

Battery Management

Proper battery configuration is critical for system performance and longevity.

Battery Types Supported: Flooded Lead-Acid, AGM, Gel, Lithium (with compatible BMS).

Charging Stages: Bulk, Absorption, Float, Equalization (for flooded batteries).

Equalization: Periodic overcharge to prevent stratification (configurable interval and duration).

Low Battery Protection: Automatic shutdown when battery voltage drops below set point to prevent damage.

Care & Maintenance

Regular maintenance ensures optimal performance and longevity.

1. Keep unit clean and free of dust accumulation.
2. Check terminal connections periodically for tightness and corrosion.
3. Monitor battery condition and electrolyte levels (for flooded batteries).
4. Check ventilation paths are unobstructed.
5. Update firmware when new versions are available.

CAUTION! Disconnect all power sources before performing any maintenance. Do not use compressed air for cleaning as it may drive dust into components.
