Rich Solar RS-CBK2500 2500W 48VDC-120VAC Solar Kit
The Rich Solar RS-CBK2500 2500W 48VDC-120VAC Solar Kit is a complete 48V solar power package built for cabins, tiny homes, remote buildings, workshops, off-grid properties, and backup power systems that need solar input, lithium battery storage, and 120VAC inverter output in one matched package. With 2500W of solar panels, two ALPHA 5 PRO 5.12kWh lithium batteries, and one NOVA 6500S 48V hybrid inverter, this kit gives customers a strong foundation for a serious single-inverter battery-based power system.
Product Overview
The RS-CBK2500 is designed for customers who need more than a basic solar charging kit, but do not need the dual-inverter 240VAC version. It combines solar generation, lithium battery storage, and a 120VAC hybrid inverter into one coordinated 48V system package.
This kit is a strong fit for off-grid cabins, tiny homes, workshops, remote buildings, and backup power projects where 120VAC output is the right fit for the intended loads. It provides the major system components needed for solar collection, battery storage, and inverter output, while still requiring proper system design, installation, protection equipment, permitting, and code-compliant electrical work.
What Comes in the Kit
The RS-CBK2500 includes the major components needed for a 48V 120VAC solar power system: solar panels, lithium batteries, one hybrid inverter, solar extension cables, mounting brackets, and a PV DC quick disconnect.
Ten MEGA 250W monocrystalline panels create a 2500W solar array. These panels feature a 16-busbar cell configuration, anodized aluminum frame, AR-coated tempered glass, plug-and-play junction box, and quick-connect cables that can work in series or parallel designs.
Two ALPHA 5 PRO 51.2V 100Ah LiFePO4 batteries provide approximately 10.24kWh of storage. Each battery is rated at 5120Wh and features a built-in BMS, 7,000-cycle life, UL1973 / UL9540A / FCC certification, and 100A continuous charge and discharge capability.
One 6500W 48V off-grid hybrid inverter creates the 120VAC inverter foundation for the system. The NOVA 6500S platform includes pure sine wave output, UL certification, built-in Wi-Fi, BMS communication support, generator or utility input compatibility, and parallel operation capability for properly planned expansions.
Additional Included System Components
In addition to the panels, batteries, and inverter, the kit includes core solar-side hardware to help support installation planning and panel wiring.
Built for Cabins, Backup Power, and 120VAC Off-Grid Loads
This kit is built for customers who need real solar production and lithium battery storage, but want a single 120VAC inverter setup instead of a larger split-phase configuration. It is especially useful for customers powering essential loads, cabin circuits, workshop equipment, remote structures, and backup systems where 120VAC output matches the project.
Key System Highlights
This description keeps the focus on the real buying decision: solar production, usable battery storage, 120VAC inverter capability, 48V architecture, system expandability, and practical use cases.
The ten included MEGA 250W panels provide a 2500W solar array for charging the 48V battery system. The panels are designed with quick-connect cables, AR-coated tempered glass, and strong low-light performance for real-world solar production.
Two ALPHA 5 PRO batteries give the system approximately 10.24kWh of lithium storage. The LiFePO4 chemistry, BMS protection, long cycle life, and parallel expansion capability make the battery side a serious upgrade from small portable power solutions.
The included NOVA 6500S inverter supports a 48V system configuration with 120VAC pure sine wave output, built-in Wi-Fi monitoring, generator or utility input compatibility, and BMS communication support through RS485, CAN-BUS, or RS232.
Instead of piecing together unrelated components, this kit gives customers a matched set of Rich Solar panels, ALPHA 5 PRO batteries, NOVA hybrid inverter hardware, solar cables, brackets, and a PV disconnect for a cleaner system starting point.
