B. INSTALLATION B-1 SAFETY B-1-1 Positioning 1. Do not put the PIP-LC on rugged or declined surface. 2. Do not install the PIP-LC system near water or in damp environments. 3. Do not install the PIP-LC system where it will be exposed to direct sunlight or heat. 4. Do not block ventilation openings in the PIP-LC system or leave objects on top of the PIP-LC. 5. Keep the PIP-LC far away from heat-emitting sources. 6. Do not expose it to corrosive gas. 7. Ambient temperature: 0°C - 40°C 8.
B-1-2 Transporting 1. Disconnect all power cables if necessary. 2. Be careful not to drop/damage the PIP-LC while transporting. 3. Don‘t move the PIP-LC upside down. 4. Please transport the PIP-LC system only in the original packaging (to protect against shock and impact). B-1-3 Installation 1. Connect the PIP-LC system only to a grounded shockproof wiring system to avoid electric shocks resulting from current leakage. 2. Place cables in such a way that no one can step or trip over them. 3.
B-2 MOUNTING 1. 2. Make sure a wall surface or a solid place can support the PIP-LC. Mark the bracket hole positions of the PIP-LC on the wall. 3. Use a screw driver to fix the PIP-LC 4. If more holes are required to be drilled on the bracket, make sure no metal shavings are left inside the PIP-LC. It could result in a short circuit when PIP-LC is operating. Hole Diameter 800W~2400W 4000W~8000W Upper Hole 9.
B-3 WIRING B-3-1 Inspection 1. The system may be installed and wired only by qualified electricians in accordance with applicable safety regulations. 2. When installing the electrical wiring, please note the nominal amperage of your incoming feeder. 3. Inspect the packaging carton and its content for damage. Please inform your shipper immediately should you find signs of damage. Please keep original packaging in a safe space for future use. 4.
3. DC Input Terminals - Array (Input): * Make sure the open circuit voltage (Voc) of the PV array is less than the DC maximum input voltage and the short circuit (Isc) is less than the DC maximum charging current of the built-in solar charge controller. See SPECIFICATION for more details. Recommended DC wire size for PV input: Capacity Size 800W 1.6KW 2.4KW 5.5mm2 (AWG 10) 4.0KW 6.0KW 8.0KW * Make sure electric polarity is correct when connecting DC terminals.
4. Fuses and breakers: Properly sized fuses and breakers should be installed between each important junctions, i.e. PV <-> Controller, Controller <-> Battery, Battery <-> Inverter, and Inverter <-> AC loads. As a general rule of thumb, follow the formula below when selecting a properly sized fuse/breaker: Amp = 1.25 * Isc of ccircuit ircuit current For more information, please consult your electrician for guidance. 5.
connection. * Inverter may be turned OFF, but can still carry live electricity. WARNING: if you intend to service the inverter, please ensure all power sources (AC, battery etc) are all disconnected. Also, capacitors inside the inverter may still carry charge and it is strongly disconnected recommended that the capacitors are first discharged before working with internal PCBs to avoid damage to system. The above battery resistor can be used to discharge the capacitors. 7.
C. OPERATION C-1 PRIOR TO STARTUP 1. Ensure the PIP-LC is in a suitable positioning. 2. Check and ensure all inputs cables are secured. 3. Make sure the load is disconnected or in the “OFF” position. 4. Check if input voltage meets the PIP-LC rating required. 5. Ensure batteries, loads (turned off), and AC cables are properly connected before switching on the PIP-LC. C-2 OPERATIONS OPERATIONS PROCEDURES Please follow the instructions below for PIP-LC operation. 1. Connect AC source (optional).
C-3 OPERATION MODES C-3-1 PIPPIP-LC System Block Diagram C-3-2 AC Priority / AC Mode System default is AC priority mode. There are two main loops when AC utility is normal: the AC loop and the battery charging loop. The AC output power comes from AC utility input and passes through static switch to support power to load. The battery charging voltage comes from AC utility input and converted by AC/DC charger to support battery-charging power.
C-3-4 Battery Mode (AC utility failure) When there is insufficient solar power and AC power is unavailable, the system will enter Battery mode. In this mode the PIP-LC will convert all power from battery bank into usable AC electricity, thereby supplying power to loads.
D. SYSTEM STATUS This section contains information on the system status that can be displayed via PIP-LC’s LCD screen. Use Up/Down key to select/display various system parameters as shown in LCD below. This screen will refresh once the system power is enabled.

5. Inverter Charging Voltage Chart Under DC priority (Inverter mode), the inverter will transfer to AC line mode after the battery low shutdown. And then the AC power continues to charge the batteries. When the batteries are boost-charged up to the highest voltage like the A point (14.5/29.3/58.5Vdc) in the drawing, the inverter will start to count count for 2 hours and then it can back to inverter mode again.
