The storage layer buffers solar output against charging demand; no single catalog product covers the full combination as one SKU.<\/p>\n<h2>Why Developers Are Asking About This Now<\/h2>\n<p>Industrial parks and microgrid sites increasingly need to add <span style=\"color: #ff6600;\"><strong><a style=\"color: #ff6600;\" href=\"https:\/\/treocharge.com\/fr\/categorie\/station-de-recharge-ev\/\">EV charging<\/a><\/strong><\/span> load without triggering a grid-capacity upgrade. Pairing that load with on-site solar and a storage buffer is one way to do it, since the battery can absorb midday PV surplus and discharge it during charging peaks rather than pulling everything from the grid connection in real time. The International Energy Agency&#8217;s Electricity 2026 report frames this kind of demand-side flexibility as an increasingly central piece of grid planning as EV charging load grows faster than transmission capacity in many markets.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/treocharge.com\/wp-content\/uploads\/2026\/03\/solution-2-1.webp\" alt=\"Solution de stockage d&#039;\u00e9nergie C&amp;I\" \/><\/p>\n<h2>What &#8220;One Site&#8221; Actually Means Architecturally<\/h2>\n<p>Three distinct equipment categories sit behind this framing, and treating them as one purchasable product tends to create confusion during procurement.<br \/>\nSolar generation is project-specific \u2014 panel count, inverter sizing, and site layout depend entirely on available roof or ground area and local irradiance, and TREASURE does not manufacture PV modules or solar inverters directly.<\/p>\n<p>Battery storage is where TREASURE&#8217;s C&amp;I Integrated <span style=\"color: #ff6600;\"><strong><a style=\"color: #ff6600;\" href=\"https:\/\/treocharge.com\/fr\/armoire-de-stockage-denergie-integree-100kw-233kwh\/\">Energy Storage Cabinet<\/a><\/strong><\/span> Series fits. The series is disclosed at two fixed ratings \u2014 a 100 kW \/ 233 kWh cabinet and a 135 kW \/ 261 kWh cabinet \u2014 with multi-cabinet configurations scalable to multi-MW and multi-MWh projects. Both use lithium iron phosphate cells and support grid-connected, off-grid, solar-plus-storage, and microgrid configurations, with EMS and SCADA integration for coordinating with a site&#8217;s broader control system.<\/p>\n<p>EV charging is the load-serving layer. Depending on site constraints, this could mean fixed DC fast chargers, TREASURE&#8217;s Mobile EV Charging Robot Series for sites without permanent charging infrastructure yet, or the Plug-and-Play Mobile EV DC Fast Charging Station (241 kWh \/ 120 kW) where a self-contained, relocatable unit is preferable to trenching for a fixed connection.<\/p>\n<h2>How the Pieces Connect<\/h2>\n<p>The coordination point is the energy-management layer, not a single wire. TREASURE&#8217;s storage cabinets support Modbus TCP, Modbus RTU, CAN, and project-specific IEC protocols, which is what allows a site controller to read PV output, battery state of charge, and charging demand together and decide in real time how much power draws from solar, from storage, or from the grid.<\/p>\n<p>A typical sequence looks like this:<\/p>\n<ul>\n<li>Confirm the load profile. Fleet size, charging schedule, and peak simultaneous demand determine how much storage capacity is actually needed as a buffer versus how much is oversizing.<\/li>\n<li>Size the storage cabinet(s) against solar output and charging peaks, not against nameplate charger power \u2014 a charger rarely runs at full rated power for its entire connected session.<\/li>\n<li>Select the charging hardware based on whether the site needs fixed infrastructure now or wants to defer that civil work with mobile equipment.<\/li>\n<li>Specify the communication protocol the EMS will use to coordinate all three layers, since this determines which PCS, inverter, and charger models are actually compatible with each other.<\/li>\n<li>Confirm grid-interconnection requirements with the local utility before finalizing storage cabinet count, since export limits and demand charges vary by jurisdiction and directly affect sizing.<\/li>\n<\/ul>\n<h2>The Edge Case Most Site Plans Miss<\/h2>\n<p>A common planning mistake is sizing the storage cabinet purely against total daily solar generation, without checking it against the site&#8217;s peak simultaneous charging demand. A depot with ten EVs charging back-to-back through the afternoon can draw more instantaneous power than the storage system was sized to discharge, even if the battery has plenty of total energy left for the day. The 100 kW and 135 kW power ratings on TREASURE&#8217;s two disclosed C&amp;I cabinet models are the ceiling for how fast the battery itself can discharge \u2014 that number needs to be checked against the charging equipment&#8217;s combined peak draw, not just against total kWh needed.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/treocharge.com\/wp-content\/uploads\/2026\/03\/solution-2.webp\" alt=\"Syst\u00e8me de stockage d&#039;\u00e9nergie\" \/><\/p>\n<h2>What This Doesn&#8217;t Tell You<\/h2>\n<p>TREASURE\u2019s <span style=\"color: #ff6600;\"><strong><a style=\"color: #ff6600;\" href=\"https:\/\/treocharge.com\/fr\/solution\/\">C&amp;I storage cabinet series<\/a><\/strong><\/span> has published power and energy ratings, chemistry, and protection details for its two disclosed models, along with a stated IP67 rating for the 233 kWh cabinet specifically. What isn&#8217;t available as a packaged offering: a combined solar-plus-storage-plus-charging bill of materials, a standard reference design, or a fixed price for the integrated system. Each of the three layers is procured, sized, and quoted separately, and the EMS integration work connecting them is project-engineered rather than off-the-shelf. If your timeline assumes a single SKU and lead time for the whole system, that assumption doesn&#8217;t match how this is currently delivered.<\/p>\n<p>Compared to vendors who market a single branded &#8220;solar EV charging&#8221; product without breaking out the storage and charging components separately, this three-layer framing is more work to specify upfront \u2014 but it also means each component&#8217;s actual rated capacity is verifiable against a published spec sheet rather than a marketing bundle.<\/p>\n<h2>Pricing<\/h2>\n<p>Pricing is provided on a project-by-project basis and depends on energy capacity, charging power, voltage architecture, connector standard, battery configuration, PCS selection, enclosure design, communication protocol, software integration, logistics, commissioning, and other project requirements. Because this is a multi-component system, expect separate line items for the storage cabinet(s), charging hardware, and integration\/commissioning work rather than one combined figure.<\/p>\n<h2>FAQ<\/h2>\n<h3>Q: Does TREASURE sell a single product that combines solar, storage, and EV charging?<\/h3>\n<p>A: No. TREASURE manufactures the storage cabinet and charging hardware layers; solar generation equipment and site-specific integration are project-engineered around those two product lines rather than sold as one packaged SKU.<\/p>\n<h3>Q: Which TREASURE storage cabinet fits a mid-size industrial park?<\/h3>\n<p>A: TREASURE discloses two fixed ratings \u2014 100 kW \/ 233 kWh and 135 kW \/ 261 kWh \u2014 with multi-cabinet scaling for larger sites. The right choice depends on your peak simultaneous charging demand, not just total daily energy needed.<\/p>\n<h3>Q: Can mobile chargers be used instead of fixed chargers in this kind of setup?<\/h3>\n<p>A: Yes. TREASURE&#8217;s Mobile EV Charging Robot Series and the Plug-and-Play Mobile EV DC Fast Charging Station are both options for sites that want to add charging load without immediate fixed infrastructure construction.<\/p>\n<h3>Q: What communication protocol connects the storage and charging systems?<\/h3>\n<p>A: TREASURE&#8217;s C&amp;I storage cabinets support Modbus TCP, Modbus RTU, CAN, and project-specific IEC protocols. The exact protocol used depends on the EMS and charging equipment selected for the specific project.<\/p>","protected":false},"excerpt":{"rendered":"<p>A combined solar, storage, and EV charging system is a site design where PV generation, a battery energy storage cabinet, and EV charging equipment share one electrical and control architecture instead of operating as three separate installations.
