Rich Solar RS-CBK1302 13kW Off-Grid Hybrid Inverter & 30.72kWh Battery Kit
The Rich Solar RS-CBK1302 is a large 48V off-grid power kit built around two NOVA 6.5kW hybrid solar inverters and six ALPHA 5 PRO server rack LiFePO4 batteries. Designed for high-capacity backup power, off-grid homes, cabins, workshops, and larger energy storage projects, this kit gives you a powerful inverter foundation with expandable lithium battery storage.
Kit Includes
This kit combines the core inverter, battery, busbar, and cable components needed for a larger 48V off-grid hybrid power setup.
Product Overview
The Rich Solar RS-CBK1302 is designed for customers who need more than a small backup system. With two 6.5kW hybrid inverters and six 5.12kWh ALPHA 5 PRO batteries, this kit provides a strong foundation for larger off-grid and backup power applications where battery capacity, inverter output, and future expandability matter.
The included NOVA 6548 inverters support pure sine wave output, MPPT solar charging, generator or utility charging, Wi-Fi monitoring, parallel operation, and configurable charging priorities. This makes the system flexible for off-grid homes, backup power installations, workshops, cabins, and solar storage projects that need a more capable power platform.
The included ALPHA 5 PRO batteries use lithium iron phosphate chemistry with a built-in battery management system for overcharge, over-discharge, overcurrent, and short-circuit protection. Each battery provides 5.12kWh of storage, giving this kit a total included storage capacity of 30.72kWh before any future battery expansion.

Built Around ALPHA 5 PRO Battery Storage
The ALPHA 5 PRO batteries are designed for larger energy storage systems that need long cycle life, low maintenance operation, and reliable lithium performance. Each included battery provides 5.12kWh of storage and communicates through RS485, RS232, and CAN ports for compatible system integration.
With six batteries included, this kit is well suited for customers who want a serious storage bank from the start instead of building capacity one battery at a time.
Powered by NOVA 6548 Hybrid Inverters
The two included NOVA 6548 inverters provide the power conversion and charging control for the system. Each inverter supports solar charging, AC charging, configurable charge priority, mobile monitoring with Wi-Fi, and communication options for battery management integration.
This inverter platform is designed for off-grid applications where solar input, battery storage, generator or utility charging, and pure sine wave AC output need to work together in one system.
Installation & Compatibility Note
This is a high-capacity electrical system and should be planned carefully before purchase. System design should account for AC load requirements, solar array sizing, battery capacity, wire sizing, overcurrent protection, grounding, ventilation, permits, and local electrical code requirements.
