Rich Solar 13000W 48V 120/240VAC Complete Off-Grid Solar Kit | 2500W Solar | 10.24kWh Battery

The Rich Solar 2500W 120/240VAC Off-Grid Solar Kit Gives a Home or Cabin Split-Phase Power From Two 6500W Inverters, Ten Panels and 10.24kWh of Storage

The Rich Solar 2500W 120/240VAC Off-Grid Solar Kit (RS-CBK2500240) is a complete 48V system with two NOVA 6500S off-grid hybrid inverters, two ALPHA 5 PRO 51.2V 100Ah LiFePO4 server rack batteries and ten MEGA 250 solar panels. Together the inverters deliver 13,000W of continuous pure sine wave power with a 26,000W surge rating and 120/240V split-phase output. The array totals 2,500 watts, and Rich Solar estimates about 9.0kWh of solar energy per day under 4 peak sun hours, stored in a 10.24kWh battery bank.

Rich Solar names this kit the 2500W 48VDC-240VAC Solar Kit and lists it for homes, cabins, workshops, farms, remote properties and whole-home backup power. PV extension cables, Z-bracket mounts for all ten panels and a PV DC quick disconnect are included.

Rich Solar 2500W 120/240VAC Off-Grid Solar Kit Features

120/240V Split-Phase Output for 240V Loads

Two NOVA 6500S (RS-H6548S) inverters work together to supply 120/240V split-phase power, so you can run 240V appliances as well as standard 120V circuits. Rich Solar rates the pair at 13,000W continuous and 26,000W surge. Each inverter puts out 120VAC ±5% with a 13,000VA surge rating, 91% peak efficiency and a pure sine wave.

Dual 120A MPPT Solar Chargers

Each inverter includes an MPPT solar charger that accepts up to 8,000W of PV (4,000W x 2) and charges at up to 120A. Each one also charges from utility or generator power at up to 120A, with a maximum combined charge current of 120A per inverter. The MPPT operating range is 90 to 230VDC, and the maximum PV open-circuit voltage is 250VDC.

10.24kWh LiFePO4 Battery Bank

Each ALPHA 5 PRO (RS-B5121P) is a 51.2V 100Ah lithium iron phosphate battery that stores 5,120Wh, for 10,240Wh across the pair. Rich Solar lists a 7,000-cycle life, 100A maximum charge current and 100A maximum discharge current for each battery. A built-in battery management system provides over-charge, over-discharge, over-current and short-circuit protection, and the batteries are certified to UL 1973 and UL 9540A.

Ten MEGA 250 Panels With Z-Bracket Mounts

Each MEGA 250 (RS-M250) panel is rated 250W, with 18.9V at maximum power, 13.2A at maximum power and 22.8V open-circuit voltage. The panels use AR-coated tempered glass, an anodized aluminum frame and a plug-and-play junction box, and each one measures 60.6 x 29.9 x 1.2 inches and weighs 26.9 pounds. Ten Z-bracket sets of four cover every panel.

Wi-Fi Monitoring and Configurable Priority

Each inverter has built-in Wi-Fi for monitoring on Android and iOS, RGB status lights and an event data log. You can configure AC and PV output priority and usage timers, adjust the charging current and select the AC input voltage range for home appliances or computers. Each inverter has a BMS communication port (RS485, CAN-BUS or RS232), and the batteries offer RS485, RS232 and CAN ports.

Real-World Applications

Homes and cabins. Run 120V circuits and 240V appliances from solar and battery power, within the 13,000W continuous rating.

Workshops and farms. Supply outbuildings that need 240V equipment along with standard outlets.

Remote properties. Work from about 9.0kWh of daily solar under 4 peak sun hours, and connect a generator for charging when the weather turns.

Whole-home backup. Connect utility power to the inverters' AC inputs so the system can switch to battery power, with a transfer time of 10 ms for computers or 20 ms for home appliances.

Practical Comparison

Split-Phase Kit Versus a Single 120VAC Inverter

A single NOVA 6500S puts out 120VAC. This kit pairs two units for 120/240V split-phase output and 13,000W of combined continuous power, so it can run 240V loads that a single 120V inverter can't.

Solar and Battery Versus a Generator Alone

A generator alone has to run whenever you need power. This kit stores solar energy in a 10.24kWh battery bank and still accepts generator input for charging when solar falls short.

Buyer Guidance

Size Battery Loads to the Two Batteries

Each ALPHA 5 PRO is rated for 100A maximum discharge current, so the two batteries together supply up to 200A at a nominal 51.2V, or about 10,240W. That is less than the inverters' combined 13,000W rating, so plan heavy loads that run from the batteries alone with that limit in mind. You can add more ALPHA 5 PRO batteries in parallel for larger capacity.

Plan Wiring and Protection With Your Installer

The kit list includes no busbars, battery cables or breakers, and Rich Solar doesn't give cable sizes or a wiring diagram for this kit. Have a qualified installer plan the battery cabling, DC and AC protection and PV string layout. Keep each PV string's open-circuit voltage under 250VDC, and keep the inverters within their 14°F to 104°F operating range and 5% to 95% non-condensing humidity.

This May Be A Good Fit If

• You need both 120V and 240V power at a home, cabin, farm or workshop
• Your daily use fits about 9.0kWh of solar under 4 peak sun hours plus 10.24kWh of storage
• You want Z-bracket mounts included for every panel
• You plan to add batteries as your needs grow

Common Questions

Can This Kit Run 240V Appliances?

Yes. Rich Solar lists 120/240V split-phase AC output from the two NOVA 6500S inverters, rated 13,000W continuous and 26,000W surge combined.

How Much Energy Does the Array Produce?

Rich Solar estimates about 9.0kWh per day under 4 peak sun hours from the ten 250W panels. Your results will vary with sun hours, season and shading.

Can the Inverters Use a Generator?

Yes. The NOVA 6500S works with utility mains or generator input, and each inverter can charge the batteries at up to 120A from AC power.

What Warranty Comes With the Kit?

Rich Solar lists a 3-year warranty on each NOVA 6500S inverter and a 10-year warranty on each ALPHA 5 PRO battery. The MEGA 250 panels carry a 25-year output warranty and a 10-year workmanship warranty.
