How to choose a good solar battery manufacturer?
An experienced solar manufacturer cannot be judged only by his company’s years of experience, but also by the company’s general experience in the technology market, its success, the innovative solutions used and projects in the energy sector.
Cost-effectiveness of its solar battery products
One of the most important aspects in the case of investing in batteries is the price of energy storage and its adequacy for the quality of the equipment offered. When creating a ranking, the consumer or distributor needs to focus on the manufacturer’s competitiveness in this regard and the ease of access to information on the price of the equipment provided by the company.
The warranty promise given by the manufacturer
Solar battery manufacturers offer warranties on their equipment for various time frames – from 6 to 15 years. Everything here also depends on the terms of the warranty, as sometimes it is granted, for example, only for the control module of the device. Of course, we need to take into account the warranty terms offered by the manufacturer at the time of purchase, which will be in the best interest of the user. The warranty period offered by the manufacturer is particularly important for its customers in two ways: the longer the warranty period, the greater the manufacturer’s confidence in the reliability of the equipment, the higher the user’s comfort level, and the user can be sure of unforeseen additional costs arising from the need to repair the energy storage unit over the years.
Pre-sales and after-sales service
From the user’s or installer’s point of view, an extremely important factor is the consultant’s attitude towards the customer, professionalism, substantial knowledge in the selection of the energy storage phase for the PV installation, and the fact that action is necessary in case of service. Equally important is the statement of assisting the investor in obtaining funding for the energy storage facility. So this is also an important aspect in assessing a good solar battery manufacturer.
Feedback from users
What their customers think about a particular manufacturer’s products and services is very important. Of course, the same solar batteries will naturally not work equally well for every installation, and this is kept in mind when listening to the opinions on the quality of service provided by these solar battery manufacturers.
Certifications held by the manufacturer
Certifications from the energy technology industry are an extremely important aspect to look for when you are choosing a solar battery manufacturer. This is of course for the reasons of safety, efficiency and reliability that can be guaranteed by the solar battery manufacturer. Among the certificates and tests carried out, the most important ones are those with the following markings: UL 1973, UL9540, VDE AR 4105, TOR D4, G98/99, CEI0-21, EN 50438, AS/NZS 4777.2, UN 38.3, IEC 61000-6-1, IEC 61000-6-3, IEC 62109-1, IEC 62040-1, IEC 60730-1, VDEC 60730-1, VDEC 6109-1, VDEC 62040-1, VDEC 60730-1. In addition, it is important that the manufacturer can have the TüV CE UN38.3 safety certificate.
The electrochemical technology used
It is well known that the most efficient cells for solar batteries are considered to be those manufactured using lithium-ion (Li-ion) technology. However, what should receive more attention is whether the manufacturer uses lithium iron phosphate (LiFePO4) technology for energy storage batteries. Because it is this LiFePO4 cell that ensures a higher level of safety, efficiency and longevity than other types of lithium-ion batteries. Of course, not all LiFePO4 cells are the same, and some manufacturers use used LiFePO4 cells, which can be judged by the battery’s Gravimetric Specifific energy, usually the larger the Wh/kG value, the better the cell.
Manufacturer's production capacity
In today’s rapid development of energy storage, having strong and fast delivery capacity can help distributors or installers to occupy the market faster, so the manufacturer’s production capacity is also an important factor to consider, for example, brands like Tesla, Pylontech, BYD, etc. also face the problem of oversupply, which is very unfavorable to the development of the market.
