The Rich Solar RS-CBK1250 is a 48V solar, lithium battery and hybrid inverter package for professionally planned cabin, recreational vehicle, tiny home, accessory dwelling unit and off-grid power systems using the included NOVA 6500S inverter. It includes five MEGA 250 monocrystalline solar panels, one NOVA 6500S 6,500W 48V off-grid hybrid solar inverter, one ALPHA 5 PRO 51.2V 100Ah LiFePO4 server-rack battery, listed solar extension cables, eight RS-ZB4C Z-Brackets and one photovoltaic direct-current quick disconnect. The included panels provide 1,250W total rated photovoltaic capacity, while the battery provides 5.12kWh nominal energy before operating losses, reserve settings, temperature conditions and load demand are considered. The inverter accepts up to 8,000W photovoltaic array input and supplies up to 6,500W rated 120V AC output for properly configured systems. Battery-to-inverter wiring, additional protection equipment, grounding, array string design, mounting design, permitting, load planning and final installation must be completed or confirmed for the exact application before operation.
This package includes five Rich Solar MEGA 250 panels, each rated at 250W, for 1,250W of total rated photovoltaic capacity. The current panel datasheet identifies the RS-M250 as a 250W 12V module using N-Type TOPCon multi-busbar cell technology, high-transmission anti-reflective coated tempered glass and an anodized aluminum alloy frame. Final panel stringing and protective equipment must stay within the inverter’s documented photovoltaic voltage and current limits.
The included ALPHA 5 PRO battery, model RS-B5121P, provides 51.2V nominal voltage, 100Ah nominal capacity and 5,120Wh nominal energy. Rich Solar documents closed-loop communication support, a built-in circuit breaker, rack-mount construction, low-temperature charge protection, RS485, RS232 and CAN communication ports, and at least 7,000 cycles with at least 70% capacity retention in the current specification sheet.
The included NOVA 6500S inverter, model RS-H6548S, is rated for 6,500VA / 6,500W output with 48V battery operation and 120V AC output. It includes maximum power point tracking solar charging, pure sine wave output, built-in Wi-Fi monitoring, RGB status indication, a 5-inch liquid crystal display, battery-management-system communication pathways and parallel capability for supported multi-inverter designs.
The RS-CBK1250 package lists one 30-foot 10 AWG extension cable, one 10-foot 10 AWG extension cable, eight RS-ZB4C Z-Brackets and one photovoltaic direct-current quick disconnect. These included parts support solar-side system assembly, but Rich Solar’s included-components list does not identify battery-to-inverter cabling, all required breakers, photovoltaic surge protection, grounding materials, structural mounting provisions or other code-required installation hardware as included.
Five MEGA 250 panels provide 1,250W of rated solar capacity for a professionally configured 48V battery-based power system.
The NOVA 6500S inverter and ALPHA 5 PRO battery combine 6,500W rated AC output with 5.12kWh nominal lithium storage.
