Layer - Solar Street Lighting Inverters

• Photovoltaic lamp posts for street and urban lighting

• PWM (Pulse Width Modulation) type regulation of battery charge
• Charging system for lead-acid / AGM / NiCd / Li-Ion batteries (selectable by display)
• Battery charge with voltage compensation versus temperature
• Main parameters monitoring and acquisition for the correct system operation
• Double output for separate supply of two lamps
• Inside quartz clock
• Lamps turning on/off periods management through turning on/off time setting
• Battery discharge control through connected electric load decrease (possible lamp 2 turning off or light flux
• decrease on request)
• Total turning off of the connected electric load (CUT-OFF threshold), in case of attainment of max allowed
• discharge threshold
• Lamps turning on/off through outside photocell (or using the same photovoltaic module as sensor on request)
• Lamps turning on and management through external commands (optional radio-command)
• Light flux regulation up to 50% for a best stored energy time management (on request)
• Predisposition for proximity sensor (on request)
• Display (optional)
