+<p class="texte">
+We believe that home/small office enery storage can help the grid to use less carboned electricity. We I.T. people use lots of electricity, but we should decarbonate a maximum to stop using fossil ressource (or use the less we can).
+</p>
+<p class="texte">
+This energy storage also can be used as big UPS to be "off grid" when electricity costs are too high or avoid having a bigger electricity contract. For example store the evergy in the night when electricty cost less and use the battery with the grid have more power to start machines that needs a spike of energy.<br/> 
+Coupling this with solar panel on roof or somewhere else this can allow on bright days to be more or less off-grid, or use it to recharge electrics cars with energy that is exceeded the home/small office battery.
+</p>
+<p class="textetitre">Hardware used</p>
+<p class="texte">
+We prefer the following hardware for energy storage :
+<ul>
+ <li><b>Victron Energy</b> one of the best hardware in the domain</li>
+ <li><b>Pylontech</b> for batteries</li>
+</ul>
+</p>
+<p class="texte">
+Contact us about your plans of energy storage, we can work to make the project being live.
