The Rich Solar RS-CBK2500240 is a 48V solar, lithium battery and dual-inverter package for professionally planned cabin, recreational vehicle, tiny home and off-grid power systems that require a supported 240VAC kit configuration. It includes ten MEGA 250 monocrystalline solar panels, two NOVA 6500S 6,500W 48V off-grid hybrid solar inverters, 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. Each inverter is rated for 6,500W 120V AC output, and the two-inverter setup must be wired, configured and commissioned correctly for the intended 240VAC system design. Battery-to-inverter wiring, dual-inverter configuration, 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 documented photovoltaic voltage, current and input-power limits for the installed inverter configuration.
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-system protection and documented RS485, RS232 and CAN communication ports for supported systems.
The RS-CBK2500240 package includes two NOVA 6500S inverters, model RS-H6548S. Each inverter is rated for 6,500VA / 6,500W output with 48V battery operation, 120V AC output, pure sine wave power and built-in maximum power point tracking solar charging. The dual-inverter setup is intended for the supported 240VAC kit configuration only when wired, configured and commissioned according to current Rich Solar instructions.
The RS-CBK2500240 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, inverter interconnection wiring, 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.
Two NOVA 6500S inverters and two ALPHA 5 PRO batteries support a planned 120/240V system with 10.24kWh nominal lithium storage.
