SAFETY NOTICE
ATTENTION: The following contains important safety and operating instructions. Read
and keep this manual for future reference.
1. Before installing or using the unit, read all instructions and cautionary markings on the unit, the
batteries, and all appropriate sections of the manual.
2. CAUTION- Do not disassemble the unit. Take it to a qualified service center when service or repair
is required. Incorrect re-assembly may result in a risk of electric shock or fire.
3. To reduce risk of electric shock, shutdown and disconnect all wirings before attempting any
maintenance or cleaning. Turning off the unit alone will not reduce the risk of shock or injury.
4. CAUTION – Only qualified personnel can install this equipment.
5. NEVER charge a battery below specified minimum temperature; refer to the battery data sheet.
6. Wire size is critical for safe operation, and optimal performance of the equipment. Refer to a
accredited sizing resource or cable manufacturer specifications to meet inverter/charge requirements.
7. Use caution when working with metal tools on or around all systems and batteries. Risk of electrical
arcs and/or short circuiting of equipment can lead to severe injury and damage.
8. Strictly follow installation procedure when connecting and disconnecting AC or DC terminals. Refer to
INSTALLATION section of the manual for details.
9. The included breaker is not a guarantee of battery protection. Size and install the correct over current
protection for the batteries if not included with the product.
10. GROUNDING -This inverter/charger should be connected to a permanent grounded wiring system.
The grounding system must meet the Authority Having Jurisdiction (AHJ) requirements in your area.
11. NEVER short AC output and DC inputs. Do NOT connect to the grid with a shorted DC input.
12. Warning!! Only qualified service persons are able to service this device. If errors still persist after
following troubleshooting table, please contact your retailer for further assistance.
13. WARNING: Because this inverter is non-isolated, only three types of PV modules are acceptable:
Mono-crystalline, Polycrystalline with class A-rated, and CIGS modules. To avoid any malfunction, do
not connect any PV modules with possible current leakage to the inverter. For example, grounded PV
modules will cause current leakage to the inverter. When using CIGS modules, please be sure NOT to
ground.
14. CAUTION: DC breakers and surge protection on PV lines is recommended. Without breakers the
equipment is at higher risk of damage from sources such as surges and lighting strikes.
