Rich Solar RS-CBK1250 1250W 48VDC-120VAC Solar Kit
The Rich Solar RS-CBK1250 is a complete 48V solar power package built for cabins, sheds, tiny homes, remote buildings, workshops, essential-load backup projects, and off-grid systems that need solar input, lithium battery storage, and 120VAC inverter output in one matched kit. With five MEGA 250W solar panels, one ALPHA 5 PRO 5.12kWh battery, and one NOVA 6500S 48V hybrid inverter, this system gives customers a serious step up from basic panel-and-controller kits.
Product Overview
The RS-CBK1250 is the entry point into Rich Solar’s 48V complete solar kit lineup. It is smaller than the larger 2500W and 4000W systems, but it still includes the big pieces customers actually care about: solar panels, lithium storage, inverter power, solar wiring accessories, mounting brackets, and a PV DC quick disconnect.
This is not just a solar charging kit. It includes the battery and inverter hardware needed to collect solar energy, store it in a 48V LiFePO4 battery, and convert that stored power into usable 120VAC output for compatible loads.
Explore the Main System Components
This kit is built around three major pieces: the solar array, the lithium battery, and the hybrid inverter. Use the tabs below to show customers what each part does in the system.
Solar Array
The five-panel solar array gives this kit enough panel capacity to support a real 48V battery-based power system. It is a strong fit for customers who want more than a small RV-style kit but do not need to jump into the larger multi-battery packages right away.
Battery Storage
The ALPHA 5 PRO gives the system a clean server-rack style lithium storage foundation. It is built for customers who want a more serious battery platform than portable units or small 12V batteries, with room to expand later if their power needs grow.
Hybrid Inverter
The NOVA 6500S is the heart of the system, converting stored 48V battery power into 120VAC output for compatible appliances, tools, electronics, and essential loads. It also gives the kit a more capable foundation than smaller standalone inverter setups.
What Comes in the Kit
The RS-CBK1250 bundles the core hardware needed for a 48V / 120VAC solar power system, including panels, battery, inverter, solar extension cables, mounting brackets, and a PV DC quick disconnect.
The solar array collects energy for the 48V battery system.
Server-rack style lithium storage for the complete kit.
Hybrid inverter for converting stored battery energy into 120VAC power.
Solar-side accessories help support the installation plan.
How This System Works
The solar panels collect power, the ALPHA 5 PRO battery stores it, and the NOVA 6500S inverter converts the stored 48V DC energy into 120VAC power for compatible loads. The result is a compact complete kit for customers who want a real 48V solar system without jumping straight into a larger 2500W or 4000W package.
This kit gives customers the core pieces of a 48V system in one package: solar production, lithium storage, inverter output, and the supporting solar-side hardware.
The included inverter gives the system a serious output foundation, making it suitable for customers who need more capability than a small inverter or portable power station setup.
The included ALPHA 5 PRO battery gives the system a clean lithium storage starting point with room to expand later as power needs grow.
The five included panels create a strong solar charging foundation for cabins, sheds, workshops, tiny homes, remote buildings, and selected backup power projects.
Best Fit for Smaller 48V Solar Builds
This kit makes the most sense when the customer wants a complete 48V system, but does not need the larger solar array or extra batteries included in bigger packages. It is a cleaner option for smaller off-grid properties and essential-load projects that still need serious inverter capability.
Best Uses
- Small off-grid cabin power systems
- Tiny home and remote building solar setups
- Workshop, shed, barn, and outbuilding power
- Essential-load backup power projects
- 48V solar energy storage systems
- Customers upgrading beyond portable power stations
- Properties that need solar production plus lithium battery storage
- Single-inverter 120VAC off-grid system designs
- Projects that need a complete kit without stepping into a larger 2500W system
