Want a 48V foundation without starting with a huge solar array? Five MEGA 250 panels, an ALPHA 5 PRO battery, and a NOVA 6500S inverter provide a starting point for a planned off-grid system. There is room to design a compatible expansion, but the included battery and array are sized for more modest daily energy needs than the inverter rating alone suggests.
Factory kit: RS-CBK1250. This is a component-based solar system requiring installation, with 1250W of rated solar capacity and 5.12kWh of nominal battery storage.
Why choose this kit?
- 5 rigid monocrystalline panels for 1250W of total rated solar capacity.
- 5.12kWh LiFePO4 storage for power use after sunlight fades.
- Pure sine wave 120V AC inverter for compatible equipment, within battery limits.
- MPPT solar charging and factory-specified connection hardware.
- Separate components allow the installation to be laid out for your space.
Best use cases
- Small cabins and tiny-home projects
- Barn lighting and selected 120V loads
- Systems planned for compatible future expansion
Match both running watts and startup demand to the complete system. Whole-home coverage, central air conditioning, and electric heating should not be assumed.
What is included?
- 1 x 6500W 48V Off-grid Solar Inverter (RS-H6548S)
- 5 x MEGA 250 12V 250W solar Panels (RS-M250)
- 1 x ALPHA 5 PRO 51.2V 100Ah Server Rack Lithium Battery (RS-B5121P)
- 1 x 10 AWG 30 ft Extension Cable (RS-30102)
- 1 x 10 AWG 10 ft Extension Cable (RS-10102)
- 8 x Z-Bracket Sets (one set of 4) (RS-ZB4C)
- 1 x PV DC Quick Disconnect (RS-i4)
Only the listed components are included. Appliances pictured in diagrams, installation labor, permits, transfer equipment, and site-specific materials are not included unless expressly listed.

Power and installation planning
The included battery has a 100A maximum discharge rating. At 51.2V nominal, this represents approximately 5120W DC before inverter losses, below the 6500W inverter rating. Additional compatible storage may be needed for full inverter output.
Rich Solar estimates about 4.5kWh of solar energy per day with four peak-sun hours. Actual production varies with weather, season, shading, temperature, cable losses, charge limits, and battery state of charge. This estimate is not a daily guarantee, and AC energy available from the battery is lower than nominal capacity.
A qualified installer should verify string voltage and current, cold-weather open-circuit voltage, battery configuration, grounding, fusing, cable sizing, mounting loads, and local requirements. Follow the current manuals and delivered component nameplates. Never backfeed a home through an outlet; building backup circuits need appropriate transfer or isolation equipment.
Rich Solar's current NOVA 6500S page lists higher solar-voltage limits than older kit text. Confirm the delivered inverter revision before designing an expanded array. The included single inverter supplies 120V, not 240V.
Frequently asked questions
Does 1250W describe the AC power I can use?
No. It describes rated solar-array capacity. The inverter is rated at 6500W, while stored energy is 5.12kWh. The battery's discharge limit and the installation can restrict usable power below the inverter rating.
How long will the battery run my equipment?
Runtime depends on average load, inverter consumption, usable battery energy, temperature, and reserve settings. Divide usable watt-hours by average load watts for a rough estimate, allowing for conversion losses. Send us your appliance list for sizing help.
Is this a plug-and-play portable generator?
No. It is an installation kit. Components must be mounted, wired, configured, and protected correctly before operation.
Can I add panels or batteries?
Compatible expansion may be possible after checking controller ratings, battery compatibility, charging settings, cable size, overcurrent protection, and available mounting space. Do not exceed any component limit.
Can this kit run a 240V pump or appliance?
No. This configuration supplies 120V single-phase AC. A 240V load needs a different, properly designed system.
What warranty applies?
Coverage is component-specific, not one blanket kit warranty. Verified terms are listed in the specifications above. Manufacturer exclusions and installation requirements apply; contact us to confirm coverage for your application.
