4.4 System operation

 

The XOLTA Compact BESS is operated from the XOLTA Cloud. 

 

4.5 Maintenance requirements

 

The XOLTA Compact BESS is designed to require no maintenance.

 

However, to ensure longevity of the battery, it is good practice to undertake the following from time to time:

 

– Check to see that there is nothing leaking from the system

 

– Make sure nothing is covering the heat sink (e.g., leaves, dirt, etc.)

 

– Remove dust from the system according to safety instructions described in Chapter 1

 

Any abnormalities (e.g., leakage, noise, odor) should be reported to XOLTA support.

 

4.6 Lifetime and system reliability

 

 

The XOLTA Compact BESS is designed to deliver top performance and reliability throughout its lifetime.  

 

Nevertheless, all battery cells degrade over time, whether in use or in standby operation. This is a natural  

 

process common to all batteries. The electrical performance of the battery system will therefore gradually  

 

decrease during the XOLTA Compact BESS’ lifetime. This will mean that less energy is available from the  

 

battery system and that the round-trip efficiency of the system gradually reduces.

 

When purchasing the Peace of Mind agreement with the battery, the warranty for the XOLTA Compact BESS is that 

 

for 10 years or 6500 cycles (whichever comes first) at least 70% of initial battery capacity will be maintained.

 

The capacity is determined in amp hours (Ah) at a temperature of 25°C and a discharge rate of 0.2C-rate from fully 

 

charged (100% SoC). The warranty applies only if the battery system operating modes provided by XOLTA (e.g., 

 

solar energy self-consumption) are used. No other use of the battery is covered. Currently, the warranty is valid

 

for the following countries: Austria, Belgium, Denmark, France, Germany, Ireland, Luxembourg, Netherlands,  

 

Norway, Sweden, Switzerland, and the UK. The list of countries will be periodically updated.

 

The XOLTA Compact BESS is considered to be at the end of its life when its battery capacity falls below 70%  

 

of initial battery capacity. The XOLTA Compact BESS can still be safely operated after the warranty period has  

 

expired. However, operation after its capacity drops below 70% of the initial capacity is not recommended.

 

There are several measures that can be taken to maximize battery lifetime:

 

•  for long standby operation of the system, it is strongly recommended to charge/discharge system to

 

  SoC ≈ 40% and to keep it in the ambient temperature range of 10

°

C − 20

°C

 

•  the longest lifetime of the system will be achieved at ambient temperatures of +5°C to +25°C

 

4.7 Installation and commissioning

 

The installation and system commissioning guidelines are provided by XOLTA in a separate document for  

 

the installer.

 

The XOLTA Compact BESS must only be installed and commissioned by XOLTA approved installers.
