High Voltage Home Energy Storage System: Ultimate Guide

Are you fed up with the excessive power shortage in your area? Electricity is the need of the hour and its cut down can result in a lot of issues in your daily life.

Therefore, the best way to get rid of this power issue is to take help from a high-voltage home energy storage system. Power storage devices like solar systems are one of the important sources of energy for your home.

Whether you have installed a household solar system or any other power source, a voltage battery is an ultimate need. In this article, you will learn what is the best high voltage battery and how it works.

Part 1: What’s a High Voltage Battery?

High Voltage Batteries

As indicated by the name, a battery with high energy density is termed a high voltage battery. A higher energy density simply means the battery has a larger capacity to store energy. Compared to normal batteries, a high-voltage battery has a longer life span and can support a high surge of electricity.

With the advent of technology, several new batteries have been brought into the market. Out of all, the best-performing is the lithium storage battery. It has the ability and potential to store maximum power and thus act as a high-voltage battery.

Part 2: What is a High Voltage Battery Energy Storage System?

If you have installed an effective and low-current storage system in your house, it will act as a high-voltage battery energy storage system. The main purpose of a battery energy storage system is to store maximum power without affecting the energy supply in your house. Enlisted below are some common battery systems used frequently:
• 192v
• 200v
• 220v
• 384v
• 480v

Besides this, the high voltage battery energy systems protect from energy losses as they have high power voltage and resistance against the current. Commonly, two different types of storage systems are found in the market:

High Voltage Battery System

The solar industry is filled with high voltage battery systems. Unlike low voltage batteries, they have a higher discharge rate and can easily operate heavy appliances, including electric cars.

As the voltage pressure is high, so these batteries do not require any wire or conductors for working. Some of the HV battery systems are
• Solax Triple Battery
• Fox Ess Batteries
• Sofar Amass EP HV Battery

Low Voltage Battery System

A low voltage vs high voltage battery system differentiates from its unique features to a great extent. Unlike high voltage battery systems, a low voltage battery system operates below 100V. As evident, they have low power capacity and hence can support low-power appliances. Moreover, they require a solid supporting material in the form of conductors or a grid to start working.

Although they have less power capacity, they are easier to install and can be upgraded conveniently. Here are some low-voltage battery systems:
• Saft Scalable battery
• NMC batteries
• Grid-attached batteries

Part 3: What Goes into a High Voltage Battery System?

A high-voltage battery system is highly efficient and has a higher discharge rate than any other system. Moreover, a high voltage vs low voltage battery system also distinguishes from their current capacity and safety measures. Although a high voltage battery is expensive to install, it is perfect to use in household battery packs. Let’s have a look at what this system holds inside:


One of the best characteristics of a high voltage battery pack is the safety and protection it provides to the users. With a mission to supply uninterruptible energy to the system, it has the ability to supply maximum safety to all power systems.


To measure the discharge rate and power capacity of a battery system, a reliable current measurement using shunt-resistors is essential. Although shunt-based measurement requires high energy, it is typically the best way to measure the battery modulation with higher accuracy.

Capacity (SOC) & Health (SOH) Calculation

To determine the lifespan of a home energy storage system, determining its capacity and health is highly important. The energy SOH of a battery pack is defined as the maximum energy available for use in ratio to the total energy. As the health of a battery is essential for its working, you should check it in each cycle. This will not only increase its efficiency but also make the system safe to use.

Cell Balancing

The battery life and energy capacity of a battery can be easily improved by the technique of cell balancing. In it, you have to connect multiple cells in a series arrangement to make sure that maximum energy is made available for use. In this way, the efficiency of a storage system can be increased by cell balancing.

Black Box Forensics

The purpose of black box forensics is to evaluate the reliability and productivity of a high voltage home energy storage system. This is done to ensure that all batteries are known and can adjust all model parameters so as to operate the battery storage system at its best.

Electrical Connect & Disconnect

To connect and disconnect the battery in the right direction, you have to make sure the electrical connections are arranged in the right order. To connect the battery system in the right position, reverse the order. First, connect it with positive and then with negative. To disconnect the battery, connect with the negative and then with the positive.

Capacity Scalability

Increasing the capacity and productivity of your storage system is one of the vital things you should take note of. To use your power pack for a longer time, you should increase its scalable capacity by up to 38.4 kWh. This can be done by installing single or multiple inverters as per needs.

Part 4: Standalone/Modular vs Stackable Battery System

Different battery systems have different power capacities. As discussed earlier, the difference between a high voltage and low voltage battery system lies in its storage capacity. Similarly, a standalone and stackable battery system shows the following differences:

Grid Connection

The first thing that differentiates between the two is their grid connection. A standalone or modular battery system does not depend on an electricity grid. Therefore, the energy is simply stored in the battery system.

On the other hand, a stackable battery system requires multiple connections arranged in a series or parallel way. Due to this reason, a stackable system is easy to use and can run higher voltage applications.


A standalone consists of a single or multiple modules, a number of batteries and a charge controller. Moreover, for efficient working, an inverter is also a part of the modular battery system. The PV modules help in supplying alternative currents to different home appliances.

Whereas, the stackable high voltage battery pack consists of blocks of batteries arranged in series or parallel fashion. Moreover, the current measurement is separate and varies from resistors to sensors.

ESS Size

The size and weight of a storage battery system show different values depending on the battery capacity and power supply. The ESS size of a standalone battery ranges from small to medium. On the other hand, the ESS size of a stackable battery system ranges from medium to large.

Typical Installed Voltage

The typically installed voltage of a battery storage system is greater than a consumer voltage. Common typical voltage ranges from 110 to 120 volts (AC) and 220 to 240 volts (AC). For a standalone or modular storage system, the typically installed voltage is 12V to 48V. Whereas, the typically installed voltage of a stackable voltage system is 100V to 400V.

The table below shows the further differences between a standalone and stackable battery system.

Features Standalone Battery System Stackable Battery System
Voltage Measurements Integrated Integrated
Temperature Measurements Integrated Integrated
Current Measurements Integrated Separate
Safety Functions Fully internal Internally measured, sent to MCU
