ECOBSS FLEX 3L Hybrid Inverter (6–12 kW)

Q: Can I attach HECKMAN 51.2 V modules?

Not in default EcoBSS designs—FLEX 3L is validated with ECOBSS STORE 51.2 V packs. Cross-brand LV integration requires engineering sign-off.

Q: What does PowerWallet add?

Single timeline for import, export, and self-consumption—avoiding Deye's manual mode switches between selling-first and charging priorities.

Q: Deye 12K LP3 vs FLEX 3L?

Choose Deye for broader 51.2 V battery choice and GEN-port retrofit maturity; choose FLEX 3L for EcoBSS EMS + STORE industrial design language.

Q: Parallel scaling?

Consult EcoBSS documentation for multi-unit EMS—unlike Deye 10-unit CAN parallel on LP3/HP3, FLEX scaling rules are product-specific.

The ECOBSS FLEX 3L is a three-phase hybrid inverter differentiated by firmware—not raw kW—shipping with PowerWallet EMS that unifies daily buy, sell, and auto-consumption schedules stock Deye units cannot express without manual 'Selling First' toggles.

Architected for 51.2 V ECOBSS STORE energy storage stacks (L5/L10/L15), FLEX 3L targets installers who sell integrated EcoBSS ecosystems: inverter + STORE modules + cloud EMS in one commissioning workflow. CAN BMS mapping follows EcoBSS conventions; mixing arbitrary third-party 51.2 V blocks requires explicit compatibility approval—default designs use STORE series only.

PowerWallet enables tariff-aware dispatch against Georgian B2B (0.35 ₾/kWh) and B2C (0.24 ₾/kWh) profiles: charge overnight on cheap windows, discharge at peak, export when permitted—all within one daily schedule table. This reduces custom SCADA for hotels and retail chains that otherwise bolt external EMS onto Deye hardware.

Hardware parallels other 6–12 kW three-phase hybrids: MPPT PV inputs, grid backup transfer, export limiting, and App visibility. GEN-port AC Coupling may be supported per firmware revision—confirm in EcoBSS release notes before promising retrofit topology identical to Deye LP3.

Ideal for

✓ Integrators standardized on ECOBSS STORE 51.2 V aesthetics for homes and boutiques
✓ Facilities needing unified EMS without third-party SCADA licensing
✓ Clients frustrated by Deye's separate buy/sell schedule limitations
