RCT Power Battery | Solar energy storage system

RCT Power battery solar energy storage for using the potential of your solar system. The grid power storage system of energy is a central issue for owners of photovoltaic systems with grid inverters. With this solar panel battery, we offer a resource-saving and safe storage solution for the energy management of private residential and commercial buildings.

You become more independent of your energy supplier and can make your renewable solar energy system needs more efficiently. Even electricity failure is no longer an issue. Thanks to the emergency backup supply, you always have the light on. Saving money on the electric bills costs with backing up the surplus.

The high-voltage solar power batteries from RCT power guarantees maximum efficiency and independence. The modular system can be retrofitted and adapts to the requirements of the user. And implement in existing solar panel systems. Thus, the system grows as the number of consumers increases. For example, if you buy an electric car, of course in a shapely design.

Home energy storage system made in Germany

Different battery backup types are existing for storage. As we all know the sealed lead-acid batteries. Installation costs, efficiency and safety, are a big issue with these battery banks.

The lithium technology from Germany convinces through safety and longevity. The energy storage technology for solar backup power consists of lithium iron phosphate cells, and a very high-quality BMS. Lithium iron phosphate cells are among the safest li ion battery for solar energy storage.

Furthermore, they are suitable for going off-grid as power generator in combination with the pure sine wave RCT power inverter charger. These solar charge controllers use Lithium ion batteries for standalone applications. Therefore, these solar hybrid inverters are demanding a higher quality then electricity grid energy tied systems.

The amount of energy that is possible to store from your solar panels plus battery storage in these batteries is 10.5 kW. The depth of discharge is 97% of 11.5 kw. Same cells types as in electric vehicles.

In a DC cell lithiumions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compoundas one electrode material, compared to the metalliclithium used in a non-rechargeablelithium. These have a high energy density, and no memory effect!

Install a solar RCT system ensures that your home solar PV system is using and producing the electricity optimally. With an efficiency of 97% they are cost effective and you know for sure that power supply outages will no longer bother you. Become energy independence!

Lithium battery vs lead.

We do not know any better, that a cell is massive, heavy, and can can leak. If you do not use this for a more extended period, you must store and maintain carefully. So that must be done differently at a specific moment.

With this in mind, the lithium battery LiFePO4 (Lithium Iron phosphate) is created. Light in weight, but "heavy" when it comes to performance.

  1. Useful electricity storage capacity

    In contrast to lead-acid batteries, a LiFePO4 can use 100% of the nominal capacity. If you take a 100 Ah electrical storage cell, you can only use 30 to 50 Ah of the capacity with lead-acid. While a lithium battery based can deliver this full 100 Ah ( in practise 97% ).

  2. Longer service life

    A lithium LiFePO4 lasts up to 200/5000 charging cycles. A lead-acid battery, on the other hand, will fail after only 300-500 cycles, with particular attention to maintenance and proper use. The LiFePo4 cell is precisely characterized by the absence of the necessity for that care.

  3. Fast and efficient loading

    LiFePO4 batteries can very quickly charged  up to 100% capacity. The Lead batteries require an absorption phase to load the last 20% of the size. If the charger is powerful enough, the LiFePO4 is charging extremely quickly, even within 30 minutes.It's not a problem if these energy cells not regularly full charged.

    Unlike the lead variants, the LiFePO4 will have no damage. It is protected against complete discharge. While the lead-acid can be discharged entirely, the chance of damage is very high.

    This protection against deep cycle discharging takes away many worries that people typically have, and therefore makes the LiFePO4 battery worry-free in use. And that's what you want during your vacation, no worries!

  4. Little renewable energy lost

    LiFePO4 batteries are considerably more efficient in storing energy compared to lead batteries. LiFePO4 batteries charge with an efficiency of almost 100% compared to 85% for the vast majority of acid batteries. This efficiency is especially important when using daylight panels.

  5. Climate resistance

    Both lead-acid batteries and LiFePO4 lose capacity if the batteries work in cold environments. With the RCT LiFePO4, however, this loss is minimal. For example, it has a capacity of 80% at a temperature of -20˚C, whereas this is only 30% with an AGM lead battery. Lithium is also the logical choice for use in extreme cold and heat, hence the high demand for these in the professional world.

  6. Battery storage systems, Easier to install

    You can mount the LiFePO4 batteries in any position. The room does not have to be ventilated, and not to be placed in a sepperate box. They are not only small scaled, but weigh at most a quarter of the enormous weight of the lead battery.

  7. No maintenance

    LifePO4 batteries do not require maintenance. The "Battery Management System" for DC coupling, ensures that all cells are charged proportionally and balanced. The battery only needs to be charged, and it is ready for use. This charging can be done one hour before use. The AC coupling is existing in the hybrid solar inverters and batteries.

  8. Loss of stress

    When using a RCT power system, the discharge curve is almost flat. Which means that a battery with 20% capacity can give the same output as a fully charged. So it prevents many of the problems that lead batteries to have during discharge. Another significant fact is the enormous peak load that a LiFePo4 lithium can deliver.

  9. Sustainable

    Because LiFePO4 batteries last up to 10 times longer than a lead one. They are fully recyclable at the end of their life and therefore very durable.

    In the current time, it is good that climate is taken into account. Indeed a good argument for choosing the li ion battery for solar energy storage.
