Rayo4
The Onyx Line RAYO4-24-SA LV is a 4 kW single-phase off-grid solar inverter for 24 V batteries and 110/120 V AC input. It features pure sine-wave output, a 100 A MPPT charger, up to 5,000 W PV input, dual AC outputs and lithium or lead-acid battery compatibility.
Product overview
Built around real project requirements.
The Onyx Line RAYO4-24-SA LV combines a 4 kW inverter and MPPT solar charger in a compact, low-voltage platform. Designed for solar power and backup applications, it supports 24 V lithium or lead-acid batteries and 110/120 V AC input from the grid or a generator. Its pure sine-wave output delivers 4 kW of rated power with an 8 kVA surge rating. Selectable output voltages of 100, 110, 120 or 127 V and a frequency of 50/60 Hz provide flexibility for compatible electrical systems. The integrated MPPT charger supports up to 5,000 W of solar input, an operating voltage range of 60–450 V DC and a maximum PV open-circuit voltage of 500 V DC. Solar charging, AC charging and combined solar/AC charging each support a maximum battery charging current of 100 A. Key features: • Dual AC outputs. • 5-inch LCD for system status and settings. • Lithium battery activation. • RS232, RS485 and CAN communication interfaces. • Dry contact and optional CT/meter connections. • WiFi monitoring, depending on the supplied configuration. • Maximum efficiency of 92% in battery mode. • Transfer time of 10 ms in APP/UPS mode and 20 ms in GEN mode. The inverter has an IP21 protection rating, a net weight of 7.2 kg and dimensions of 422 × 325 × 110 mm without the mounting bracket. Its specified operating temperature range is −10 °C to +60 °C.
