The system also supports remote monitoring, optional generator integration and up to 6 inverters in parallel, making it suitable for both standalone commercial projects and larger scalable C&I battery energy storage systems.
Designed by EGBATT specifically to work with EGBATT high-voltage energy storage batteries, this commercial hybrid inverter offers better system compatibility, stable BMS communication and a highly competitive system cost.
Suitable for commercial solar + battery storage, peak shaving, backup power, AC-coupled retrofits, and scalable C&I energy storage systems.
Why Choose EGBATT 30-70kW Commercial Hybrid Inverter?
Reduce avoidable energy cost
Store excess daytime solar and discharge it when grid electricity is more expensive.
Time-of-use scheduling and peak-shaving strategies can reduce grid dependence when they are configured around the site's tariff and measured load profile.
Keep priority circuits operating
Use the EPS output with a correctly sized battery and critical-load panel to support selected lighting, controls, communications, refrigeration or process loads during a grid interruption.
Avoid voltage-selection mistakes
Choose a dedicated 120/208V 30kW model or a 277/480V 40-70kW model instead of adapting a residential inverter to a commercial three-phase service.
Design for growth
Start with the power needed today and plan expansion with up to six matching units in parallel, subject to the required communications, protection and system engineering.

EGbatt offers dealer customers a 10-year warranty and technical service for its energy storage battery products.
DoD describes how much of the battery's capacity has been used. A DoD of 100% means the battery is completely empty, while 0% means it is full.
SoC reflects the battery's charge level. A SoC of 100% means the battery is full, and 0% means it is empty.
C-rate, or power factor, indicates how quickly a battery can be charged or discharged relative to its capacity. A rating of 1C means the battery can be fully charged or discharged in one hour.
The battery uses Lithium Iron Phosphate chemistry and provides a cycle life of over 6,000 cycles at 90% Depth of Discharge, and over 10 years at one cycle per day.
kW (kilowatt) is a unit of power, measuring the rate of energy production or consumption. kWh (kilowatt-hour) is a unit of energy, measuring the total amount of work done or energy used over time.
EGbatt home batteries are suitable for both indoor and outdoor installation (depending on the model's protection level) and offer floor-standing or wall-mounted options. Common locations include garages, attics, or under eaves.
This depends on the load. As a realistic example, a 10kWh battery could run ten 100-watt light bulbs for 12 hours without recharging.
The number varies based on home size, energy consumption history, and personal goals (like which devices to run during an outage). For most systems, 2 or 3 batteries are installed. A detailed discussion of your needs is recommended for an accurate assessment.
Yes, it is possible, but it requires careful planning and significant investment. A true off-grid system needs a large enough solar array and sufficient battery storage to sustain your lifestyle. Cost and having an alternative energy source for when solar charging isn't possible are key considerations.
No. EGbatt focuses on building long-term relationships with business partners like battery distributors, solar equipment dealers, and installation contractors worldwide, not direct sales to end consumers.
