[PDF Version]To prevent direct lightning strikes to the electrical systems of a PV power plant, these systems must be located in the protected volume of air-termination systems. Design ac-cording to the German VdS 2010 guideline is based on class of LPS III.
In this paper, the performance of a lightning protection system (LPS) on a grid-connected photovoltaic (PV) park is studied by simulating different scenarios with the use of an appropriate software tool.
Abstract: The aim of this paper is to analyze the lightning protection model of a photovoltaic power plant, which is of great importance, in order to guarantee the smooth work of the system and avoid errors and damage to the equipment.
When installing the external lightning protection system, it must be observed that solar cells are not shaded, for example, by air-termination rods. Diffuse shadows, which occur in case of distant rods or conductors, do not negatively affect the PV system and the yield.
With all the barriers discussed in Section 3.3, the need for lightning protection on PV systems must be evaluated on the basis of the risk analysis and protection costs. Table 10 presents the recommended standards related to PV systems including PV installations, lightning protection systems and electrical installations. Table 10.
One grid-connected, ground-installed PV plant of 100 kWp nominal power was selected as the case study for the lightning performance investigation. This is a typical small PV application that is found across Europe . Such a PV system is usually connected into the low-voltage distribution system.

Battery housing fire protection is a key criterion for the safety of electric vehicles. The housing must protect passengers in the event of a fire because battery fires cannot be extinguished. In the event of a fire, a battery housing made of steel provides vital minutes for passengers and others involved in an accident.
The selectrify battery housing protects the most sensitive and expensive component of an electric vehicle and offers enormous cost advantages – without compromising on performance. And when it comes to fire protection, it is clearly superior. Battery housing fire protection is a key criterion for the safety of electric vehicles.
Life cycle assessments show that steel is the most sustainable material for battery housings. Up to two thirds less greenhouse gas emissions arise in the production of a steel battery housing compared with an aluminum design. During use, the carbon footprints of steel and aluminum battery housings are virtually identical.
Core requirements include rack separation limits, a Hazard Mitigation Analysis to prevent thermal-runaway cascades, early-acting fire suppression and gas detection, stored-energy caps for occupied buildings, and detailed safety documentation (UL).

Avoid putting lithium batteries in parallel without any protection against voltage disparity or self balancing currents. But for your question here is maybe a lead of answer : electronics. com/questions/289450/.
@Tagadac You said not to put lithium batteries in parallel without any protection. My question described a scenario where three sets of 'four 18650s connected in parallel' are connected in series.
According to the parallel principle, the current of the main circuit is equal to the sum of the currents of the parallel branches. Therefore, a parallel lithium battery pack with “n” parallel batteries achieves the same charging efficiency as a single battery, with the charging current being the sum of the individual battery currents.
Hardware-type protection board: Use special lithium battery protection chip, when the battery voltage reaches the upper limit or lower limit, the control switch device MOS tube cut off the charging circuit or discharging circuit, to achieve the purpose of protecting the battery pack. Characteristics: 1.
Cells in multi-packs must be matched, especially when used under heavy loads. (See BU-803a: Cell Mismatch, Balancing). The single-cell configuration is the simplest battery pack; the cell does not need matching and the protection circuit on a small Li-ion cell can be kept simple.
If the cost and risk don't warrant it then just parallel 4 batteries and hope for the best with a single BMS. The cells you put in parallel are no longer considered 4 cells in parallel but are now considered one cell with more capacity and able to source more current safely (if your bus is up for it.)
3.) If the battery charged in parallel does not have a lithium battery protection board, the charging voltage must be limited to 4.2V, and a 5V charger cannot be used. 4.) After the lithium batteries are connected in parallel, there will be a charging protection chip to charge and protect the lithium batteries.

The most practical protection option is usually an external, fixed firefighting system. A fixed firefighting system does not stop an already occurring thermal runaway sequence within a battery module, but it can prevent fire spread from module to module, or from pack to pack, or to adjacent combustibles within the space.
