Yes, the latest Hybrid G4 version can support installed without batteries. It will only work as the on-grid inverter until the battery is connected.

The two inverters need to be connected with the same number and model of batteries before they can be connected in parallel.

Yes, currently the following SolaX string inverters are compatible with heat-pump control (SG ready heat pump) via connecting to SolaX adaptor box：

X1-MINI G4

X1-BOOST G4

X3-MIC G2

X3-PRO G2

X1-Hybrid G4

X3-Hybrid G4

Yes, three X3-Hybrid G4 inverter can be connected in parallel without EPS parallel box. For X3-Hybrid G4, we support up to 10 inverters to do the parallel connection with an EPS parallel box.

Our newest G4 inverters have internal switch function and the EPS box is not necessary

Yes, Hybrid G4 series support Lead-acid battery, you can choose the battery type in the ‘Charger-Battery Type-Lead Acid’.

X1-Mini G3/G4

X1-Boost G3/G4

X3-MIC G2

X3-PRO G2

X1-Hybrid G4

X3-Hybrid G4

Yes, 'charge from grid' can be enabled from the inverter LCD screen or on SolaX cloud Web/ APP.

Yes, if the number of parallel X3 INV is greater than 3pcs, the EPS parallel box is necessary. The External ATS function needs to be turned on.

X1/X3-Hybrid G4, X1-Boost G4, X1-Mini G4, X3-MIC/PRO G2

X1-MINI G4, X1-BOOST G4, X3-MIC G2, X1/X3-Hybrid G4

X1-Hybrid G4, X1-FIT G4, X3-Hybrid G4, X3-FIT G4, X1-Mini G4, X1-Boost G4

Yes, Hybrid G4 supports. With dry contact connection, inverter can control generator to charge the battery basing settings of battery SOC or charging time period.

Yes

The EPS box can provide whole house loads back-up for hybrid inverter.

For X1/X3-Hybrid G4, the SolaX Matebox Advance can also achieve this function.

Yes, the maximum output power for each phase is the smaller of 50% power rate and 5kW. EPS output shares the same limitation.

Yes, you can turn it off in setting. menu- settings- eps settings- mute

10ms(UPS level) for single hybrid inverter. More than 10ms in parallel.

No

Yes, lower voltage means earler start-up.

FIT models is to store the energy for on-grid inverter, it has no port to connet PV input.

Yes, Hybrid series equipped with IP65  protection level. Pls follow the instruction of installation about the enviroment requirement

The second meter is used to monitor the power situation of the 3rd party on-grid inverter, is not necessary for the AC coupling system.

For X1-Hybrid G4, it supports up to 4×T30 or up to 3×T58 

For X3-Hybrid G4, it supports up to 4×T30 or up to 4×T58 

With the BMS parallel box, X1-Hybrid G4 can support up to 6×T58 and X3-Hybrid G4 supports up to 8×T58  

For the hybrid system, if the PV power is higher than the inverter's power, the surplus energy will be used to charge battery via DC to DC. Let's take 10kW hybrid G4 as an example, if the PV is 16.5kW, then 10kW can be converted to AC power, and 6.5kW will charge the batteries

If you disable 0 export control, excess energy will be injected to grid. If you enable 0 export control, inverter will limite generation power.

No, but it's better to work online, as we can provide remote support if there is any issue happened.

Yes, you can add the hybrid/Fit inverter into your exisiting string inverter system.

Yes, a meter or a CT is needed for export control(In the on-grid inverter series,only single phase on-grid inverters are compatible with CT,three phase on-grid inverters are not compatible with CT) . Once a meter or a CT is connected, you should configure the inverter via LCD screen(App for non-screen version). Go to setting item 'Export control' to enable meter(or CT) and then confirm how much power to inject to the grid. If you want zero injection, you just need to set the value to 0.

In the parallel system, Every hybrid inverter must have the same battery model and quantities.

The Max.PV array power is also known as the oversizing, which is 200% for our Hybrid G4. it means the maximum power of the array that the inverter can connected. And the Max. PV input power means the max power can be used by the inverter.

Yes, each inverter in the parallel system need its own pocket WiFi/LAN

No You don't need EPS parallel box if you don’t need back up function, no matter how many units in parallel.

Yes, SolaX support both X1-Matebox and X3-Matebox

Yes, with matebox advanced or EPS box.

In this sytem,  you need two meters, the first meter is at the Grid Connection Point, and the second meter is going to measure the output of the string inverters. Both meters are connecting to the hybrid inverter. Please note zero-export control is not avaialble in this system.

Yes. (Only WiFi2.0/WiFi3.0/WiFi+LAN adaptations have been updated so far)
