About TRUEFEEL HOUSEHOLD CO.,LTD.
About TRUEFEEL HOUSEHOLD CO.,LTD.
A system integrator for solar generation, power conversion, battery storage and EV charging, working with distributors, EPC contractors and energy users.
Company profile
One system boundary, one responsible team
TRUEFEEL HOUSEHOLD CO.,LTD. supplies solar modules, solar inverters, battery storage systems and EV charging hardware to distributors, EPC contractors and commercial energy users. The product lines are developed to be specified together, so a project team deals with one interface standard, one document set and one technical contact.
Our engineering work starts before quotation: load profile, site conditions and grid constraints are reviewed first, then the equipment list is derived from that model. For international projects, documentation is prepared for the target market and handed over with the shipment.
What we take responsibility for
- Interface data between modules, storage and chargers
- Documentation prepared per product line and market
- A named technical contact through commissioning
- Spare parts and field support through regional partners
Engineering and manufacturing
Module assembly and testing
Cell sorting, string soldering, lamination and EL inspection are carried out on the same line, with batch records kept for each shipment.
- Batch-level EL and power records
- Frame and junction box checks
- Pre-shipment sampling by pallet
Storage integration and factory test
Cabinets are assembled with the PCS and communication gateway, then tested against the interface table issued to the project team.
- Protocol mapping before dispatch
- Thermal and protection function checks
- Documented test reports per unit
Charging hardware and site support
Chargers are configured for the market connector and payment profile, and commissioning support is scheduled with the installer.
- Connector variants by market
- OCPP profile loaded before shipping
- Remote diagnostics after handover
Inverter configuration and firmware loading
Hybrid and string inverters are configured with the project grid code, battery profile and monitoring account before dispatch, and the settings are archived against the unit serial number.
- Grid code profile loaded per market
- Battery communication tested with the matched pack
- Settings archived by serial number

How we work
Load profile and site review
We start from consumption data, tariff structure and site constraints rather than a fixed product package.
System sizing and interface table
Generation, conversion, storage and charging are sized in one model, with every interface point listed before quotation.
Factory test and documentation
Units are configured and tested together, and the document set is prepared for the target market.
Commissioning and service
Commissioning support, handover documents and a named technical contact for the operational phase.
