The backup battery market for photovoltaic installations is beginning to be much more competitive and affordable. A good example of this are these two new products of 10 and 15 kW for less than 3,000 euros.
Little by little, the solar energy sector is becoming more affordable and advanced. Not only because prices tend to fall, but because technology advances and offers more and more performance and durability, making faster amortization possible.
But, although solar panels and inverters, that is, photovoltaic installations, have already started down this path, the same did not happen with the batteries. Until now, very interesting products at reasonable prices are beginning to emerge.
10 kWh BSL Battery
The first example of BBB (good, beautiful and cheap) batteries is the new backup battery for the home that has been presented by the Chinese company BSL battery. A product with a capacity of 10.24 kWh, with a rated output power 10kW and with peaks of up to 15 kW. Nothing to do with, for example, the 5/7 kW offered by Testa’s Powerball, which is also much more expensive.
The BSL battery, which can also be installed in a chain to reach up to 164 kW, does not give up certain relevant aspects to reduce costs. It has a built-in management system to prevent voltage swings, as well as temperature control and short circuit protection.
Not only that, “the B-LFP48-200PW battery is compatible with more than 20 inverter models of the market, such as Victron, Studer, Deye, Goodwe, Growatt, Sofar and SMA…etc”, informs our half brother Forococheselectricos.com. A battery that, in addition, is quite compact, since it offers dimensions of 680 mm x 485 mm x 220 mm and weighs a manageable 107 kg.
According to the manufacturer, it has a useful life of approximately 6,000 charge and discharge cycles, in addition to a 10-year warranty. The official sale price is 2633 euros, although when it is sent from China the final cost with shipping costs and tariffs amounts to 3074 euros. It is still, without a doubt, a much lower price than the rest of the products sold in Europe… or is it?
15kW Easy Battery
Well, no, the truth is that a Spanish company, Renovables del Sur, offers a similar product at an even more competitive price.
This is the backup battery Easy Battery EB348 ENwhich has a 15 kWh usable capacity, with an output power of 5 kW continuous. All this more than enough to cover the daily needs of a home.
according to us reports forococheselectricos.comthis battery module also integrates a smart battery management and monitoring module (BMS) active that protects against overloads that affect the useful life of the battery. Likewise, it acts against overdischarging, thus preventing the battery from working below its minimum voltage values. It also cuts short circuits automatically.
The 15 kW battery from Renovables del Sur has a Bluetooth connection to receive information via mobile and control its status in real time. Of course, it is only compatible with inverters with an operating range of 40 to 50 V. Its estimated useful life is approximately 4000 charge and discharge cyclesafter which it will continue to operate at a lower capacity.
Its price is the best of all: €2,899with taxes and shipping to the Peninsula included.
