Description
The 1.5 MVA PCS conversion cabinet has hybrid liquid-air cooling, so the power electronics work in the open air without a separate machine room. The 372 kWh battery cabinets are cooled by their own liquid loop, independent of the PCS. Discharge duration is set by the ratio of battery to power cabinets, so the same blocks make both a short 1 MVA / 1 MWh system and a 9 MVA / 33 MWh store with a discharge of more than three hours. The 1–3 MVA HES XXL SKID version is delivered assembled on a frame and is designed for connection to both low and medium voltage. The converters comply with IEC 62909-1 for bidirectional grid converters and IEC 62477-1 for power electronics safety. Electromagnetic compatibility for industrial environments is confirmed to EN 61000-6-2/-4.
How to choose
The first question when choosing concerns the connection point. For the low voltage busbars of a plant or a medium voltage grid at 1–3 MVA the HES XXL SKID version is convenient, while larger systems up to 9 MVA are built on HES XXL or HES XXL IEC from several 1.5 MVA PCS cabinets. The number of 372 kWh battery cabinets is calculated from the energy that must be delivered per cycle. If 600 kVA / 1827 kWh is enough for the site, it is simpler to take SUNSYS HES L, while a ready medium voltage container from 2.5 MVA / 5 MWh is offered by SMARTSYS M5000.

FAQ
What maximum power and capacity does SUNSYS HES XXL have?
The system expands to 9 MVA and 33 MWh. The smallest configuration has 1 MVA and 1 MWh.
Can the HES XXL be connected to a medium voltage grid?
Yes, the 1–3 MVA HES XXL SKID version is designed for connection to both low and medium voltage. The scheme for larger capacities is worked out in the project.
How much energy does one HES XXL battery cabinet hold?
One cabinet on LFP cells stores 372 kWh and has liquid cooling. The number of such cabinets determines how many hours the system holds rated power.
Which standards does the PCS converter in the HES XXL comply with?
The converter complies with IEC 62909-1 and IEC 62477-1, and EMC is confirmed to EN 61000-6-2/-4.
