The Rich Solar RS-CBK2500 is a 48V solar, lithium battery and hybrid inverter package for professionally planned cabin, recreational vehicle, tiny home and off-grid power systems. It includes ten MEGA 250 monocrystalline solar panels, one NOVA 6500S 6,500W 48V off-grid hybrid solar inverter, two ALPHA 5 PRO 51.2V 100Ah LiFePO4 server-rack batteries, listed solar extension cables, fifteen Z-bracket sets and one photovoltaic direct current quick disconnect. The included panels provide 2,500W total rated photovoltaic capacity, while the two batteries provide 10.24kWh combined 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 ten Rich Solar MEGA 250 panels, each rated at 250W, for 2,500W of total rated photovoltaic capacity. Each panel is specified with 18.9V maximum power voltage, 13.2A maximum power current, 22.8V open-circuit voltage and 13.7A short-circuit current. Final series-and-parallel array layout must remain within the inverter’s documented photovoltaic voltage, current and input-power limits.
The kit includes two ALPHA 5 PRO batteries, model RS-B5121P, each providing 51.2V nominal voltage, 100Ah nominal capacity and 5,120Wh nominal energy. Together, they provide 10.24kWh of nominal lithium iron phosphate storage before usable-capacity limits, inverter losses, temperature conditions, reserve settings and connected-load demand are considered. The batteries include battery-management protection and documented RS485, RS232 and CAN communication pathways for supported systems.
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, USB, RS232, RS485 and dry-contact communication interfaces, and parallel capability up to 6 units for supported multi-inverter designs.
The RS-CBK2500 package lists two 30-foot 10 AWG extension cables, two 10-foot 10 AWG extension cables, fifteen Z-bracket sets and one photovoltaic direct current quick disconnect. These included parts support solar-side system assembly, but the listed kit contents do not state that all battery cabling, breakers, surge protection, grounding materials, mounting structure or code-required installation hardware are included.
Ten MEGA 250 panels provide 2,500W of rated solar capacity for a professionally configured 48V battery-based power system.
The NOVA 6500S inverter and two ALPHA 5 PRO batteries combine 6,500W rated AC output with 10.24kWh nominal lithium storage.
