The high-voltage solar power batteries from RCT guarantees maximum efficiency and independence. The modular system can be retrofitted and adapts to the requirements of the user. Thus, the system grows as the number of consumers increases. For example, if you buy an electric car, of course in a shapely design.
The lithium technology from Germany convinces through safety and longevity. The energy storage for solar power consists of lithium iron phosphate cells, German connection technology and a very high-quality German BMS. Lithium iron phosphate cells are among the safest lithium-ion batteries.

The amount of energy that is possible to store from your solar panels in these deep cycle batteries is 10.5 kW. The depth of discharge is 97% of 11.5 kw. Same cells types as in electric vehicles.
In the batteries lithiumionsmove 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. The batteries have a high energy density, no memory effect(other than LFP cells)and low self-discharge.
RCT power system ensures that your solar pv system can use optimally. With an efficiency of 97% you know for sure that power cuts will no longer bother you.
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.
In contrast to lead-acid batteries, a LiFePO4 can use more than 100% of the nominal capacity. If you take a 100 Ah battery, you can only use 30 to 50 Ah of the capacity with lead-acid, while this is more than 100 Ah with a LiFePO4.
A LiFePO4 lasts just 3 to 4 times as long, up to 1500/2000 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.
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 batteries, 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 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!
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 lead batteries. This efficiency is especially important when using daylight panels.
Both lead-acid batteries and LiFePO4 batteries lose capacity in cold environments. With the RCT power LiFePO4, however, this loss is minimal. For example, a LiFePO4 has a capacity of 80% at a temperature of -20˚C, whereas this is only 30% with an AGM lead battery. LiFePO4 is also the logical choice for use in extreme cold and heat, hence the high demand for these batteries in the professional world.
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 smaller but weigh at most a quarter of the enormous weight of the lead battery.
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 exist in the hybrid solar inverter.
When using a RCT power battery, 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.
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. All components of the cell are reused. In the current time, it is good that climate is taken into account. Indeed a good argument for choosing the Lithium battery.
