The challenge
Why pair solar with storage
Where midday exports are worth less than later grid purchases, storage can shift solar generation to more valuable operating hours.
Solar peaks at noon but site demand often peaks in the morning and evening, so surplus is exported at low feed-in rates.
Rising and volatile grid tariffs make every self-consumed kilowatt-hour more valuable than an exported one.
Sites want resilience and predictable energy costs, not just a panel count.
How it works
How the system works
PV generation, Hithium storage and site loads are coordinated around the project-selected power-conversion architecture.
- 01
PV array
Tongwei 645–765 W modules generate DC power; array sizing is checked against the roof, inverter input limits and grid connection.
- 02
Power conversion
Choose either the Hithium all-in-one system with its integrated 125 kW PCS or the Hithium DC cabinet with an external Growatt WIT 63-125K-XHU three-phase C&I hybrid inverter.
- 03
Battery storage
The 261 kWh Hithium liquid-cooled battery stores surplus generation when the approved project logic and operating limits allow.
- 04
Site & grid
Configured controls allocate available solar, battery and grid power according to the selected operating mode and local grid requirements.

FAQ
Frequently asked
Should I choose a DC-coupled or AC-coupled system?
The appropriate coupling and power-conversion architecture depends on whether the project is new or a retrofit, the existing inverter topology, required operating modes and local grid rules. We review the site design before confirming the equipment scope.
