Rich Solar 4000W 48V Complete Solar Kit | 5.12kWh Battery

This is the kit to look at when you want a larger solar array with the inverter and battery equipment together in one cabinet. Ten MEGA 400 panels feed the RS-A10 all-in-one system. You get 4000W of rated solar capacity, 5.12kWh of storage, and a 6500W-rated 120V inverter—three different numbers that matter when sizing the job.

Factory kit: RS-K001-4K. This is a component-based solar system requiring installation, with 4000W of rated solar capacity and 5.12kWh of nominal battery storage.

Why choose this kit?

• 10 rigid monocrystalline panels for 4000W 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

• Fixed off-grid cabins
• Workshop lighting and selected tools within system limits
• Remote properties with a ten-panel installation area

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 × All-in-One Energy Storage System (RS-A10)

Power and installation planning

The included battery's 120A continuous limit represents approximately 6144W DC at 51.2V nominal before conversion losses. This is below the inverter's 6500W nameplate rating. Battery state of charge and operating mode also affect usable output.

Rich Solar estimates about 14.4kWh 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.

Frequently asked questions

Does 4000W 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.
