Tune your solar system with a victron battery and improve your performance. Whenever the victron battery is full the electrolyser switches on. Hydrogen management systems have the same duties the solar controllers have. A major part of costs comes from software developments. It should be as easy as possible. The VOLKS ELECTROLYSER is regulated mechanically, because these are more trustworthy, fixable and long lasting machines. But lets take the positive impact of digitalisation and use hydrogen management systems for redundant hydrogen process surveillance.
Automated function of victron battery loaded by a cerbo energy manager
The most important function of a renewable energy setup is the load management. Let’s say the batteries are full, the consumers are supplied but the sun still shines. Almost every inverter and charge controller on the market have the load function or the generator function wich can be used to switch on the electrolyser for excess PV.
connect victron battery to Energy Management with electrolyser
The electrolyser can be switched on by the so called PV-Smart port of Inverters or by dc charge Controllers.
Victron battery and Hydrogen production with Fronius Energy management
We suggest using DC directly to the electrolyser to reduce converter costs and inverter conversion losses. The Fronius Smart Meter shows the energy charts and flows. It can activate an electrolyser for excess solar or wind.
Battery storage and Hydrogen storage can be monitored with Fronius products.
Victron battery and Hydrogen implementation in the cerbo gx
We use the Victron Cerbo GX to manage off grid hydrogen applications. A Hydrogen leak detector which senses hydrogen around the electrolyser is compatible with the cerbo gx. Of corse it would also be possible to use a Raspberry pie for the hydrogen management, but the cerbo contains all the necessary features to run an electrolyser and a hydrogen energy storage safely. Online surveillance through the portal is possible.
The temperature of the electrolyser, the pressure of the hydrogen tanks and all the solar and battery relevant information can be surveyed remotely through the VRM Portal.
For Prime service clients there is the option of remote support.
SMA Sunny Home Manager 2.0 for hydrogen upgrade
Also the sunny home manager can switch loads. The SMA Sunny Home Manager 2.0 can activate the electrolyser.
Which Battery Storages are H2 ready?
The Volks-Electrolyser exists in a 12 V and 48 V Hydrogen generator version.
Is the victron battery hydrogen ready?
Definitely victron battery fit perfectly with hydrogen, especially in off-grid situations.
BYD Batteries are hydrogen ready
The BYD BATTERY-BOX PREMIUM LVL (2021) with a nominal Voltage of 51,4 Volt is suitable for hydrogen electrolysers direct DC systems. If the 12 Volt electrolyser wants to be fed by this battery count on 500 $ converter costs.
LG Battery Storages are not Hydrogen ready
The LG RESU FLEX Lithium BATTERIES work with high voltages in ranges of 200 V. The bigger the voltage difference between Source /(Battery) and Drain (Electrolyser) is, the more expensive and loss full the converter.
Temperature surveillance of electrolysers
The PEM 1 kW electrolyser should be preheated at the beginning. When the hydrogen production increases, heat can be recovered through the heat exchanger in the electrolyser.

Measurement and Control of hydrogen compressors
In order to compress hydrogen to 7000 PSI, the compressor has to be switched on when the PEM Electrolysers pressure of 700 PSI is reached.
The hydrogen compressor shouldn’t be clocking and should work to long. Therefor a pressure sensor or a pressure switch with several setpoints is needed.
In 2026 the volks-electrolyser switches this purpose mechanically through a pressure gage switch (the right gauge in the picture above). The cerbo had connectivity problems or update issues from time to time.
Electrical sensors are much cheaper though.
