Hithium battery platform
Battery modules, BMS, thermal management and the cabinet enclosure provide the storage layer.

C&I Energy Storage Systems for Commercial Projects in Europe
Sunket Supply offers two Hithium 261kWh liquid-cooled architectures: an all-in-one ESS with integrated 125kW PCS, or a DC battery cabinet confirmed compatible with an external Growatt WIT three-phase C&I hybrid inverter.
Our flagship line. Both products use Hithium prismatic LFP 314Ah cells and liquid cooling. Choose the 261kWh all-in-one with its integrated 125kW PCS, or the DC cabinet confirmed compatible with a Growatt WIT 63-125K-XHU three-phase C&I hybrid inverter. Applicable technical documentation and grid-connection requirements are reviewed per architecture, country and network operator.

Technical review
Where this is applied
These products are deployed across the following commercial and grid-scale applications.
PV + ESS
Commercial solar generation combined with battery storage for lower grid purchases and higher self-consumption.
View solution ›Peak Shaving
Battery systems discharge during demand peaks to reduce grid demand charges for factories and commercial sites.
View solution ›Self-Consumption Optimisation
Store daytime solar generation and use it when site demand is higher than PV output.
View solution ›Product FAQ
What makes a battery product a complete ESS?
A complete ESS combines battery storage with power conversion, BMS, energy-management functions and protection. In this range, power conversion is either an integrated PCS or an external Growatt WIT C&I hybrid inverter.
What does external hybrid inverter ESS mean?
It means the battery cabinet is paired with a separate external hybrid inverter instead of being fully integrated inside one cabinet.
How do the two Hithium 261 architectures differ?
The all-in-one product includes its own 125kW PCS. The DC battery cabinet instead uses a separate Growatt WIT 63-125K-XHU three-phase C&I hybrid inverter.
How is grid-code suitability confirmed?
Grid-connection requirements depend on the country, connection voltage, network operator, selected architecture and firmware. Applicable certificates, settings and control requirements are reviewed per project; final approval remains with the qualified local parties and network operator.
