Battery Centric DC Coupling

Battery Centric DC Coupling, both for Inputs and Outputs.

 A More efficient way to store energy from all sources and distribute it

What is DC Coupling? 

The core idea is simple: we connect all your energy sources: solar panels, batteries, wind turbines, and even the grid, to one central power highway. This highway only uses DC (Direct Current) power.

• The old AC coupling way: Solar panels create DC power, and batteries store DC power. In older systems, you waste energy converting DC to AC (Alternating Current) and back again from AC to DC to charge battery. Then to discharge battery you have to convert DC to AC a third time. This has losses at every conversion.

• DC Input Coupling: Our DC-coupled system acts like a direct pipeline. We send the solar power straight into the battery. This means less wasted energy, faster response times, and a lower total cost for you. This can save between 10% to 15% of the energy lost vs AC coupling.

• DC Output Coupling: From battery into Factory using a DC distribution network. DC distribution has been shown to give 10% or more energy savings. These DC networks have been pioneered by various organizations such Open Direct Current Alliance.

• Using DC directly to factory machines and processes e.g. heating, motor drives, induction,  etc. means o need for inverting, rectification, increases efficiency and high peak powers possible without any added peak costs.

• Combined energy savings can be up to 25%.

The System design

Regenset Energy uses smart technology, including Ampt String Optimizers, to make this direct connection highly efficient.

• Ampt String Optimizers: These are like specialized traffic cops for your solar panels. They ensure every single panel is working at its maximum efficiency, regardless of shade or dirt. They maximize the flow of energy straight into the battery.

• Battery-Centric Architecture: Because the battery is at the core, it can instantly share power with the entire system. This means your facility gets reliable, seamless power—no matter what the grid is doing. We prioritize clean energy first.

• AC output or future DC output - OR a hybrid, where battery energy can be shared over the DC grid as well

All Energy Sources

The best part of DC Coupling is flexibility. We can connect any energy source directly to the system:

Solar (PV)       Diesel/Biogas/ Biofuel generators

Wind The Grid

The Diesel Genset Game-Changer

DC Coupling completely changes how backup generators work.

• The Old way: A traditional Genset (Generator Set/Diesel Generator) has be large enough to meet 'peak demand', but usually has to run continually and much lower powers. This burns a lot of diesel and is a large capex installation.

• The Regenset Energy way: Our battery system handles all those peak demands instantly. This allows us to use a much smaller Genset. It runs at a slow, constant, optimal speed—like cruise control—simply to charge the battery at a steady rate.

• The Genset can Be AC coupled, BUT the genset usually uses an inefficient AC synchronous generator, and this must be rectified back to DC to charge battery. DC coupling significantly increases efficiency, as a PM generator and DC controller can be used directly to battery. 

DC coupling Result: 

Use less fuel

Spend less on maintenance 

Save money

The grid Battery Charger 

DC Coupling completely changes how AC grid is used. Simply just connect a isolated battery charger grid. No feed in certifications, costs, etc are needed. Just use the grid as a backup, lower and smooth out the power you draw from it, and only use when needed.

DC coupling Result: 

• Our battery system handles all those peak demands instantly. This allows us to use a much smaller grid connection. It runs at a lower constant power—simply to charge the battery at a steady rate.

• FULL grid isolation with much smaller rated power

• No change over time. 

• ZERO over or under voltage spikes. 

• NO chance of higher peak demand 

• No power factor or kVA charges, 

• Optimize time of use energy consumption. 

Considerably  smaller size of connection

Can optimize use energy off-peak
