Rich Solar 6500W 48V 120VAC Complete Off-Grid Solar Kit | 1250W Solar | 5.12kWh Battery

The Rich Solar 1250W Off-Grid Solar Kit Pairs Five 250W Panels With a 5.12kWh Battery and a 6500W Inverter to Power a Cabin, Workshop or Remote Building

The Rich Solar 1250W Off-Grid Solar Kit (RS-CBK1250) is a complete 48V system built around a NOVA 6500S off-grid hybrid inverter, one ALPHA 5 PRO 51.2V 100Ah LiFePO4 server rack battery and five MEGA 250 solar panels. The panels total 1,250 watts, and Rich Solar estimates about 4.5kWh of solar energy per day under 4 peak sun hours. The inverter supplies 6,500W of continuous 120VAC pure sine wave power with a 13,000VA surge rating.

Rich Solar designed this kit for cabins, tiny homes, workshops, barns, remote properties and backup power. The inverter accepts solar, battery, utility and generator inputs, and the kit includes PV extension cables, Z-bracket mounts for every panel and a PV DC quick disconnect.

Rich Solar 1250W Off-Grid Solar Kit Features

6500W Pure Sine Inverter With a 120A MPPT Charger

The NOVA 6500S (RS-H6548S) combines an inverter, an MPPT solar charger and an AC battery charger in one wall-mounted unit. It delivers 6,500W continuous at 120VAC ±5% with a 13,000VA surge rating and 91% peak efficiency. The solar charger accepts up to 8,000W of PV across two inputs (4,000W each) and charges at up to 120A. The AC charger also charges at up to 120A from utility or generator power, and total charging current tops out at 120A.

5.12kWh of LiFePO4 Storage

The ALPHA 5 PRO (RS-B5121P) is a 51.2V 100Ah lithium iron phosphate battery that stores 5,120Wh in a 3U rack-mount case. Rich Solar rates it for 7,000+ cycles at 70% depth of discharge, with a 100A maximum charge current and a 100A maximum continuous discharge current. Its battery management system protects against over-charge, over-discharge, over-current, short circuits and high or low temperatures, and it balances the cells.

Built-In Battery Heating for Cold Charging

The battery charges from 32°F to 140°F and discharges from -4°F to 149°F. A 150W internal heater turns on when the battery's internal temperature is 41°F or lower and charging current is present, and it turns off at 59°F or when the charger is disconnected.

Five MEGA 250 Panels With Mounting Hardware

Each MEGA 250 (RS-M250) panel is rated 250W, with 18.9V at maximum power, 22.8V open-circuit voltage and 21.4% module efficiency. The panels use N-type TOPCon cells, AR-coated tempered glass and an anodized aluminum frame, and each one measures 60.6 x 29.9 x 1.2 inches and weighs 26.9 pounds. Five Z-bracket sets of four give every panel its own mounts, and a 30 ft and a 10 ft 10 AWG extension cable help connect the array.

Monitoring and Source Settings

The inverter has built-in Wi-Fi for monitoring on Android and iOS, a 5-inch color LCD and an RGB status light ring. From the LCD you can set output priority to Utility First, Solar First or SBU (solar, then battery, then utility). The battery adds Wi-Fi and Bluetooth monitoring of state of charge, voltage, current and alarms in the RICH SOLAR app. A 12VDC output rated at 100W can run small DC loads such as a router.

Real-World Applications

Cabins and tiny homes. Run lights, fans, a refrigerator and electronics on 120VAC from solar and battery power.

Workshops and barns. Power lighting and equipment at an outbuilding with no utility service, within the 6,500W continuous rating.

Remote properties. Store daytime solar in the 5.12kWh battery for evening use, and connect a generator to recharge during cloudy stretches.

Backup power. With utility power on the AC input, the inverter switches to battery power when the grid fails, with a 10 ms (UPS setting) or 20 ms (appliance setting) transfer time.

Practical Comparison

1250W Kit Versus Buying Components Separately

Rich Solar matches the inverter, battery, panels, cables, mounts and PV disconnect in this kit, and the battery and inverter both communicate over RS485 and CAN. Buying parts one at a time means checking those limits yourself.

Single 120VAC Inverter Versus a Split-Phase Setup

This kit's one NOVA 6500S puts out 120VAC, which suits standard outlets and 120V appliances. The NOVA 6500S manual describes split-phase operation for 240V equipment using at least one inverter on each phase, so 240V loads would call for a different system design.

Solar and Battery Versus a Generator Alone

A generator alone has to run whenever you need power. This kit stores solar energy in the battery for later, and it still accepts a generator on the AC input to charge the battery at up to 120A when solar falls short.

Buyer Guidance

Plan the Battery Load and Wiring

The single ALPHA 5 PRO is rated for 100A continuous discharge and 5,120W maximum output, so loads that run from the battery alone should stay within that rating even though the inverter is rated 6,500W. Rich Solar's kit list doesn't include battery-to-inverter cables or breakers. The NOVA 6500S manual calls for 2/0 AWG battery cable and a separate DC over-current protector or disconnect between the battery and inverter. It also calls for a separate AC breaker on the AC input, 600VDC/30A DC breakers between the inverter and the panels, and a PV junction box with surge protection.

Solar Wiring and Mounting

The inverter has two PV inputs rated for 18A each. Keep each string's open-circuit voltage under 250VDC and above the 80V start-up voltage, within the 90 to 230VDC MPPT range. Mount the inverter vertically on concrete or another non-combustible surface, and install the battery indoors, away from water, between 32°F and 122°F. Rich Solar says qualified personnel should install the system.

This May Be A Good Fit If

• You need 120VAC power at a cabin, tiny home, workshop or barn
• Your daily use fits about 4.5kWh of solar under 4 peak sun hours plus 5.12kWh of storage
• You want the option of generator or utility charging
• You'd like phone monitoring for both the inverter and the battery

Common Questions

How Much Energy Does the 1250W Kit Produce?

Rich Solar estimates about 4.5kWh per day under 4 peak sun hours from the five 250W panels. Your results will vary with your sun hours, season and shading.

Can I Add More Batteries Later?

Yes. ALPHA 5 PRO batteries connect in parallel for more capacity. The battery manual says to set one battery as the master (address 1) to communicate with the inverter and set the others as slaves with their DIP switches. Never connect them in series, since each battery's BMS is designed for 51.2V.

Are Mounting Brackets Included?

Yes. The kit includes five Z-bracket sets with four brackets per set, one set for each panel. The MEGA 250 frame also has pre-drilled holes for ground mounts, poles and tilt systems.

What Warranty Comes With the Kit?

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