Deye hybrid inverters can be connected to GbbOptimizer in several ways. On this page you will find a checklist of inverter settings and a comparison of connection methods.

Checklist#

Before starting GbbOptimizer, verify the following on the Deye inverter:

Operating mode — Zero export to CT or Zero export to Loads (not “Selling First”!)
Do not check the operating mode during active discharge — GbbOptimizer temporarily changes the mode.
TimeOfUse — must be enabled
TimeOfUse — set to % (not V), unless an SOC-to-V mapping is defined
System Work Mode (Schedule) — enabled for all 7 days of the week
Energy pattern — Load First
SolarSell / Sell energy — checked
Grid Charge — Enable
Grid Start, Battery Restart — values lower than MinSOC
Data upload interval — every 1 min (default is every 5 min — needs to be changed)
Copilot — must be disabled

Connection methods — comparison#

The Deye inverter can be connected to GbbOptimizer in four ways:

	Solarman / DeyeCloud	GbbConnect2	DongleDirect	HomeAssistant / SolarAssistant
Data from GbbOptimizer to inverter	GbbOptimizer → DeyeCloud → Solarman → Dongle → Inverter	GbbOptimizer → GbbConnect2 → Dongle → Inverter	GbbOptimizer → Dongle → Inverter	GbbOptimizer → HA Automation → Inverter
Data from inverter to GbbOptimizer	Inverter → Dongle → Solarman → DeyeCloud → GbbOptimizer	Inverter → Dongle → GbbConnect2 → GbbOptimizer	Inverter → Dongle → GbbOptimizer	Inverter → HA Automation → GbbOptimizer
Data from DeyeCloud/Solarman to inverter	DeyeCloud → Solarman → Dongle → Inverter	DeyeCloud → Solarman → Dongle → Inverter	DeyeCloud → Solarman → GbbOptimizer → Dongle → Inverter	N/A
Data from inverter to DeyeCloud/Solarman	Inverter → Dongle → Solarman → DeyeCloud	Inverter → Dongle → Solarman → DeyeCloud	Inverter → Dongle → GbbOptimizer → Solarman → DeyeCloud	N/A
Dongle disconnection problem	Yes	No	Yes	No
Required software	None	GbbConnect2 on local network	None	HomeAssistant on local network
Data passes through Chinese servers	Yes	Yes (no, if you block Dongle at firewall)	Your choice	No
Parameter changes from outside home	Yes	No (but you can use Solarman/DeyeCloud in parallel)	Your choice	Yes

Detailed configuration instructions for each method can be found in the Connection methods section.
