Rich Solar 6500W 48V 120VAC Complete Off-Grid Solar Kit | 2500W Solar | 10.24kWh Battery

The Rich Solar 2500W 120VAC Off-Grid Solar Kit Combines Ten 250W Panels, 10.24kWh of LiFePO4 Storage and a 6500W Inverter for Cabins and Remote Properties

The Rich Solar 2500W 120VAC Off-Grid Solar Kit (RS-CBK2500) is a complete 48V system with a NOVA 6500S off-grid hybrid inverter, two ALPHA 5 PRO 51.2V 100Ah LiFePO4 server rack batteries and ten MEGA 250 solar panels. The array totals 2,500 watts, and Rich Solar estimates about 9.0kWh of solar energy per day under 4 peak sun hours. The batteries store 10.24kWh, and the inverter supplies 6,500W of continuous 120VAC pure sine wave power with a 13,000VA surge rating.

Rich Solar built this kit for cabins, tiny homes, workshops, farms, 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 all ten panels and a PV DC quick disconnect.

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

One Inverter Handles Solar, Battery, Grid and Generator Power

The NOVA 6500S (RS-H6548S) is an inverter, MPPT solar charger and 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. Its solar charger accepts up to 8,000W of PV across two inputs (4,000W each) and charges at up to 120A. Utility or generator power can charge the batteries at up to 120A, with total charging current capped at 120A.

10.24kWh Battery Bank From Two ALPHA 5 PRO Units

Each ALPHA 5 PRO (RS-B5121P) is a 51.2V 100Ah lithium iron phosphate battery that stores 5,120Wh in a 3U rack-mount case, for 10,240Wh across the pair. Rich Solar rates each one for 7,000+ cycles at 70% depth of discharge, 100A maximum charge current and 100A maximum continuous discharge current. Each battery's management system guards against over-charge, over-discharge, over-current, short circuits and high or low temperatures, and it balances the cells.

Cold-Weather Charging With Internal Heaters

The batteries charge from 32°F to 140°F and discharge from -4°F to 149°F. In each battery, a 150W heater turns on when the internal temperature is 41°F or lower and charging current is present, then shuts off at 59°F or when the charger is disconnected.

Ten MEGA 250 Panels With Z-Bracket Mounts

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. 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, and two 30 ft and two 10 ft 10 AWG extension cables help connect the array.

App Monitoring and Source Priority

Built-in Wi-Fi lets you monitor the inverter on Android and iOS, and the 5-inch color LCD lets you set output priority to Utility First, Solar First or SBU (solar, then battery, then utility). The batteries add 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, with 10.24kWh of storage for nights.

Farms and workshops. Power lighting and equipment at outbuildings without utility service, within the 6,500W continuous rating.

Remote properties. Rely on about 9.0kWh of daily solar under 4 peak sun hours, and connect a generator to recharge when the weather turns.

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

2500W Kit Versus a Single-Battery System

Each ALPHA 5 PRO is rated for 100A continuous discharge and 5,120W maximum output. With two batteries in parallel, this kit doubles both the storage and the current the bank can deliver, which gives the 6,500W inverter more room for heavy loads at night.

Single 120VAC Inverter Versus a Split-Phase Setup

The one NOVA 6500S in this kit puts out 120VAC for 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 for later use, and it still accepts a generator on the AC input to charge the batteries at up to 120A when solar falls short.

Buyer Guidance

Plan the Battery Wiring and Protection

Rich Solar's kit list doesn't include battery-to-inverter cables, a busbar or breakers. The NOVA 6500S manual calls for 2/0 AWG battery cable and a separate DC over-current protector or disconnect between the batteries 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. The ALPHA 5 PRO manual asks for parallel battery cables of the same length and specification, and it says never to connect the batteries in series.

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 batteries 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, farm building or workshop
• Your daily use fits about 9.0kWh of solar under 4 peak sun hours plus 10.24kWh of storage
• You want generator or utility charging as a backup source
• You'd like to monitor the inverter and batteries from your phone

Common Questions

How Much Energy Does the 2500W Kit Produce?

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

How Do the Two Batteries Work Together?

The ALPHA 5 PRO batteries connect in parallel. Per the battery manual, you set one battery as the master (address 1) with its DIP switches so it communicates with the inverter over RS485 or CAN, and set the other as a slave. You can add more ALPHA 5 PRO batteries in parallel later for more capacity.

Are Mounting Brackets Included?

Yes. The kit includes ten 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 each ALPHA 5 PRO battery. The MEGA 250 panels carry a 25-year power output warranty and a 10-year workmanship warranty.
