This week we put a product under the Microscope’s magnifying glass: the TOPzS batteries.
To talk about them is today with us Josep Ollé, Head of the technical department of Renobat Batteries:
MR: Josep, Thank you for dedicating this time, I know you’re busy. Let’s remind readers a little TOPzSproduct, Tell us your main features
JO: in principle they are identical to the traditional OPzS; They are stationary batteries, of low antimony content, and therefore of low maintenance and with an acid density of 1, 24kg/l.
MR: then the difference with the known OPzS is only physical, the container?
JO: indeed, They only differ in the container and the Formats. Instead of using transparent SAN containers (Estirenoacrilnitrilo), which are very expensive, we have chosen to use almost transparent PP (polypropylene) containers, which also allow the perfect visualization of the plates, and that when treated In addition to a flexible material they are more resistant to possible blows in the Transport. In the factory, the assembly has been changed from a semi-manual process to an automated 100% Production. The combination of both factors has allowed us to create a battery of characteristics identical to the OPzS in C10 regimes, with the substantial advantage of a price adjustment, in line with the current situation, up to 30%.
MR: after 5 years in the market, how has the product been carried?
JO: Considering that it is a relatively new product, on the outside and even by name, it tends to arouse certain suspicions when deciding for it, despite the competitive price. The principles have been quite hard due to the Customer’s caution, the isolated photovoltaic market is very traditional in this sense and the installers do not want to take risks when assembling one of the most expensive elements of the Installation. Despite all this, after the first years it has been possible to take a significant quantitative leap, thanks mainly to the field results have been quite forceful.
We have not received the return of any item in warranty so far, Which proves that they are just as reliable as the traditional OPzS from the technical point of VIEW. We can say that the test time to elapsed and that the trend towards this new battery is clearly ascending. For me it has been a resounding success.
MR: Josep Thank you very much for illustrating the product, I am convinced that the installers will increasingly change to this new model, who can resist a value for money so excellent?
JO: indeed, Maintaining benefits has achieved a much more efficient production process that has been moved to prices. Thanks to You.
