When you've decided on a home battery backup system, how do you find the best home battery for your needs? Key figures, such as the charge and discharge performance of the power storage capacity or storage unit are important benchmarks.

Why Are Key Figures For Home Power Backup System So Important?

A solar power backup system should be well matched to the solar system in question in terms of capacity, performance and service life. If the residential battery storage is too small, the capacity may not be sufficient to use all the electricity from your PV system. On the other hand, if you choose a residential battery storage that is too large, its capacity will not be fully utilized by your system. Since larger battery storage units are significantly more expensive than smaller ones, the costs for the solar power backup system may eat up the potential savings from the use of self-generated solar power.

But the right dimensioning is also important from a technical point of view, because the service life of a battery can be significantly reduced by insufficient charging - a phenomenon that you may also be familiar with from your car battery. Your purchase decision should therefore be based on the fact that your home solar power backup system can be adapted as well as possible to your individual operating conditions. By the way, modern battery storage systems for electricity nowadays often have an emergency power function, which is very useful in the event of a power failure and, unlike the emergency generator, does not require any fuel.

Key Figures That Help You Decide

First of all, it is important to clarify which key figures exist for battery backup systems. Based on these key figures, you can ask yourself which of them are decisive for your purchase.

Overview Of Key Figures For Battery Backup Systems

● Cell chemistry: 

Cell chemistry refers to the materials that make up the batteries in your power storage unit. While for a long time lead-acid or lead-gel batteries were particularly popular for use in the private sector, lithium-ion batteries are now more commonly used. Due to their high energy density, these have established themselves on the market in recent years. Cell phones, laptops and electric cars also make use of this composition. Do you prefer inexpensive lead batteries or expensive lithium-ion batteries, which are more efficient?

● Charging and discharging power (kW)?

The maximum charging and discharging capacity indicates the amount of power (in kilowatts) with which the storage unit can be charged and discharged. The higher the capacity, the faster the storage unit can be charged when the sun is shining and the larger the consumers that can be supplied with the stored electricity. The charging and discharging power you need for your electricity storage unit depends on the consumers you want to supply with it. The charging and discharging power of the BSLBATT is scalable, for example, the 10.12kWh Powerwall is 9.8kW, but when you use two modules in parallel, the power becomes 18.6kW. Importantly, this is not possible for all battery brands, such as LG Chem.

● Storage capacity or nominal capacity: 

This is specified by the manufacturer in kilowatt hours (kWh) and should always match the PV power.

● Usable storage capacity:

This often differs from the theoretical nominal capacity in practice because the final depth of charge reduces the actual capacity.

● 1-phase or 3-phase?

Inverters and battery inverters can be 1-phase or 3-phase and differ based on the amount of power they can feed into the home grid. 1-phase solar storage systems can feed up to 4.6 kW into the grid, which is ideal for most residential purposes, while 3-phase systems are well-suited for powering larger loads or in combination with photovoltaic systems with particularly large numbers of modules.

Whether a 1-phase or 3-phase electricity storage system is the right choice for you thus largely depends on the associated inverter.

Depth of discharge:

To protect the solar battery from damage due to deep discharge, it can only be discharged to a final depth of charge specified by the manufacturer. This affects the actual usable battery capacity.

Charging cycles: 

A distinction is made between full cycle (from full charge to maximum depth of discharge) and micro cycle (minor discharge and recharge). The service life of a battery storage unit is largely defined by the number of charge cycles.

Efficiency of residential storage system: 

The efficiency of the residential storage system is measured in terms of efficiency. Under optimal conditions, the efficiency of electricity storage systems is 90& to 98 %, which is very efficient. However, this value can vary based on the model, ambient temperature, and how the storage unit is handled during charging and discharging. Due to electronic control via inverters and charge controllers, every storage system loses a few percentage points compared to the theoretically achievable performance. Overall, modern electricity storage units have a low conversion loss, which means they provide high-performance energy conversion. Lead-acid batteries have a lower efficiency than lithium-ion batteries (approx. 75 % vs. approx. 90 %).

Cycle life: 

Just like your solar system, a residential solar battery is constantly operating to store the solar energy generated on the roof of your house. The equipment life of a storage system is shorter than that of a solar module. Lead-acid storage systems can last up to 10 years, while lithium-ion storage systems can last at least 20 years. Most manufacturers offer a 10-year warranty on your residential solar battery. Regardless of the number of charge cycles, batteries have a limited life expectancy. At the end of the cycle life, the original rated power is reduced to about 80 %.

Charging and discharging power of the home battery backup system: 

This indicates how much power the power storage unit can be charged or discharged with. The greater the charging power, the faster the battery is charged in sunshine. The higher the discharge power, the larger the connected power consumers can be.

Why Are Charge And Discharge Performance Of Residential Battery Backup So Important?

In fact, many users focus on key figures such as efficiency, battery capacity and service life when selecting a residential battery backup. In doing so, they often neglect the charging and discharging performance of the lithium batteries. However, this is very important for operating devices with electricity from PV systems. If your power backup system has a rather low charging capacity, it takes longer for the lithium batteries to be fully charged again. However, it is really problematic if the discharge capacity of residential battery backup is too low.

Logically, the operation of electricity-intensive appliances such as your washing machine or dryer is most worthwhile with free solar power. However, such power-hungry appliances are only supplied with energy via the residential battery backup if it has a sufficient discharge capacity. In addition to individual consumers with a great hunger for electricity, a large number of smaller appliances can also push the battery backup system to its limits. So even if you don't have any large consumers in mind when you buy, you should consider future purchases. This is especially true for charging an electric car with self-generated PV power. In case of doubt, the discharge capacity of your residential battery backup should be somewhat more generously dimensioned.

Expandability and Retrofittability?

The integration of a wallbox for your electric car or the expansion of your household through new or larger application have an impact on your annual electricity demand. Thanks to a subsequent expansion of your home battery storage system, you can continue to sustainably cover your household electricity consumption.

As a rule, however, it is worthwhile to buy a larger home solar battery when purchasing the solar system including storage in order to avoid a later expansion and to cover such changes in electricity demand. (BSLBATT can provide the largest home lithium battery on the market with a single capacity of 20kWh.) If you still decided to buy a smaller storage battery system when purchasing your solar system, an expansion of your home battery storage system is still no problem in most cases.

You already have a solar system, but without a home battery storage system? Our experts will be happy to advise you on the selection of the right residential storage system for your existing PV system.

Finding The Right Charging And Discharging Capacity For Your Power Backup System

The charging and discharging capacity of home battery for PV systems usually depends on the lithium battery size or its capacity. Smaller batteries usually also have lower discharging power or charging power. However, high power ratings and large storage capacity are associated with higher purchase costs. Therefore, when buying, you should consider the following factors:

● Consumption patterns: If you need electricity primarily when the sun is not shining, the home battery backup system must be larger than if you use most of the energy during the day.

● Annual power consumption: Depending on the number and consumption patterns of the residents, you should consider the average annual power consumption when choosing the home battery storage.

● System size: As mentioned at the beginning, the size of the home battery and the size of the system must be matched. If the PV system generates more electricity than you can store, this is just as unfavorable as an unnecessarily large and expensive battery backup system that is only partially used.

● Degree of self-sufficiency: If you are aiming for greater self-sufficiency from the power grid, the home battery must also be larger.

● Self-consumption: The more electricity you want to generate for self-consumption, the more battery backup system capacity you need. If, on the other hand, you want to feed more electricity into the public grid, the home battery storage can be dimensioned smaller.

Battery backup system make it possible to use the solar electricity generated at a later point in time. Electricity that is not consumed directly does not necessarily have to be fed into the public grid immediately. Instead, the photovoltaic self-consumption increases and thus also the savings. Because of the decreasing feed-in tariff, a high level of self-consumption is economically particularly profitable. So you save money with every kilowatt hour of solar power that you consume.

At the same time, you are doing something good for our environment by making the best possible use of your solar energy. In order to benefit from the advantages of your own photovoltaic system, you should also buy a home solar battery. You can find out which model is right for you in our BSLBATT Website.
