What Is All In One Energy Storage System?
An all in one energy storage system (ess) is a plug-and-play power solution that provides clean and reliable electricity. It integrates components such as batteries, inverters, battery management systems, and communication interfaces, making it highly suitable for users who wish to simplify the installation and maintenance process.
The integrated energy storage system allows you to power your load using both the solar grid and the public utility grid simultaneously. The storage system stores energy when electricity rates are low and releases it during peak usage times to reduce electricity expenses.
All In One Energy Storage System By Feature
We are professional manufacturers of all in one ess, capable of customizing a wide range of specifications including voltage, current, capacity, and power to meet user needs. If you do not have specific requirements yet, you may begin by browsing the following standard products.
Benefits Of All In One Solar Battery System
Built-In Smart BMS Guarantee The Safety
The all-in-one solar battery utilizes Grade A lithium iron phosphate (Lifepo4) cells, which are extremely stable chemically and have passed a series of safety tests.
Moreover, the battery is equipped with an intelligent BMS (Battery Management System) that monitors the battery status and cuts off the power if parameters exceed safe limits, effectively preventing overcharging, over-discharging, over-current, short-circuiting, and other adverse events.
Certified Excellence –
Batteries with Global Accreditation
Our batteries comply with international safety standards, have undergone rigorous safety assessments, and have obtained certifications such as CE, UL, MSDS, IEC, KC, and PSE.
If you are looking for an all-in-one battery that meets international certifications, please feel free to contact Delong.
Excellent Summit Efficiency For Your Project
Conversion efficiency refers to the efficiency of an all-in-one ess during the process of electric energy conversion and storage, including energy loss during charging and discharging. This metric is crucial for achieving a balance between cost and benefit. Inverter efficiency, battery efficiency, system design, and operational conditions all impact this figure, with the efficiency of the inverter affecting the entire system.
Delong ensures high system efficiency by using Grade A lifepo4 cells, an excellent BMS and thermal management system design, and an inverter with an efficiency of over 93%. All these measures are aimed at improving your energy usage efficiency and helping you see benefits sooner.
Save Your Cost? Yes!
The all-in-one energy storage system is a long-term project that involves initial investment, operational costs, performance, and long-term savings. So how do they balance cost and benefit for you, and expedite your return on investment?
Energy storage systems typically save on expenses by storing surplus electricity and releasing it during peak usage times. Our system has a conversion efficiency of 93%, minimizing your energy loss and saving on electricity costs.
Besides efficiency, it is also essential to choose a durable and reliable storage system. For example, our all-in-one energy storage system from Delong is expected to last about 12 years with virtually no maintenance, helping you to achieve break-even more quickly.
Furthermore, many governments offer financial subsidies and tax incentives for renewable energy and energy storage systems, which can significantly reduce your initial investment and accelerate your return on investment.
