Safety Precautions

Read all safety instructions before installation or operation.

Electrical Safety: Disconnect all power sources before working on system. Use insulated tools.
Battery Safety: Keep batteries away from fire, water, and extreme temperatures. Use protective gear.
Installation Safety: Use proper mounting hardware. Ensure roof/ground structure can support weight.
Fire Safety: Install disconnect switches and circuit breakers as per local codes.

WARNING! High voltage present during operation. Only qualified electricians should perform electrical connections. Follow NEC and local regulations.

Unpacking & Components

Unpack carefully and verify all components against packing list.

Solar Panels: Check for cracks or damage to glass and frames.
Battery Modules: Inspect for dents, leaks, or damaged terminals.
Inverter/Controller: Ensure no physical damage to casing or ports.
Accessories: Verify all cables, connectors, mounting brackets, and manuals are present.

CAUTION! Report any missing or damaged components immediately. Do not install damaged parts.

Installation Guide

Site Selection: South-facing (Northern Hemisphere) with minimal shading. Roof or ground mount.
Mounting Panels: Use provided aluminum rails and clamps. Follow tilt angle recommendations.
Battery Location: Install in well-ventilated, temperature-controlled area (ideal 50°F-77°F).
Inverter Placement: Mount on wall near main electrical panel, protected from elements.
Wiring: Use proper gauge cables. Keep DC and AC wiring separated. Use conduit where required.

Electrical Configuration

Connect components in correct sequence. Turn OFF all power sources during connections.

Connect solar panels in series/parallel to achieve desired voltage/current.
Connect panels to charge controller using PV input terminals.
Connect batteries to inverter/charge controller with proper polarity.
Connect inverter AC output to main electrical panel via dedicated breaker.
Connect grid input (if grid-tie) to inverter grid input terminals.
Connect system controller to inverter and network.

Tip: Label all cables and connections. Torque terminals to specifications in manual.

System Setup & Commissioning

Power on system and configure settings via controller or app.

Initial Power-Up: Turn on DC disconnect, then AC disconnect. Inverter should initiate self-test.
Controller Setup: Connect to WiFi/Bluetooth. Use Back40 Solar App to create account and register system.
System Configuration: Set operation mode (Grid-tie, Off-grid, Hybrid). Configure battery parameters.
Grid Settings: Enter utility parameters (voltage, frequency) if grid-tied.
Test Operation: Verify solar charging, battery charging/discharging, inverter output.

WARNING! Commissioning must be performed by qualified personnel. Verify all settings before final operation.

Monitoring & Control

Monitor performance and control system via Back40 Solar App or web portal.

App Features: Real-time power production/consumption, battery state of charge, energy history, alerts/notifications, remote mode changes, firmware updates.

Settings: Adjust charge rates, set backup priorities, schedule operations, configure grid sell/buy parameters.

Maintenance Guidelines

Regular maintenance ensures optimal performance and longevity.

Solar Panels: Clean surface every 6 months with water and soft cloth. Inspect for debris or shading.
Batteries: Check terminals for corrosion quarterly. Ensure ventilation is clear.
Inverter/Controller: Keep vents clean and unobstructed. Check for error codes.
Connections: Inspect wiring annually for wear, looseness, or damage.
Software: Update firmware via app when notifications appear.

CAUTION! Disconnect system before cleaning or maintenance. Do not use abrasive cleaners on panels.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power output	Tripped breaker, blown fuse	Check DC/AC disconnects and breakers. Reset if tripped.
Battery not charging	Poor sunlight, faulty connection	Check panel connections and shading. Verify charge controller status.
Inverter error code	Overload, temperature, grid fault	Refer to error code in manual. Reduce load, cool environment, check grid voltage.
App not connecting	Network issues, controller offline	Check WiFi/Ethernet connection. Reboot controller. Verify app permissions.
Low system efficiency	Dirty panels, wiring losses	Clean panels. Check for loose or corroded connections.
Battery draining fast	High load, old battery, cold temp	Reduce consumption. Check battery health. Ensure operating temperature.

Reset: Controller > Settings > System > Reset to factory defaults if needed.
