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
No, only one heat pump can be connected to one Adaptor Box G2.
Yes, actually string inverters doesn't have battery management unit integrated. SolaX provides a string inverter + retro-fit + battery storage solution, which makes it possible to extend battery storage to existing string inverter system.
The on-grid inverter can be offline at sunset without enough solar input. If you still want to monitor your system at night, you will need SolaX on-grid inverter with a built-in AC auxiliary power supply(APS) and SolaX smart energy meter/CT to achieve 24 hours energy monitoring.
The two inverters need to be connected with the same number and model of batteries before they can be connected in parallel.
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 BMS Parallel Box II G2 could support T30 batteries, and it can parallel with 1 to 8 piecies T30 batteries.
No, Solax EV charger can work as standalone charger, the green and eco mode are extra features that allow you can use renewable energy generated by solar inverter and wind turbines.
Yes, it is necessary to change the "Grid Data Source" from "Inverter" to "Meter".
Our newest G4 inverters have internal switch function and the EPS box is not necessary
No
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.
It means the power that was bought from the grid.
In automatic control mode, the Adaptor Box G2 communicates via RS485, obtains on-grid data, SoC of battery and so on, and then responds to it after internal logical judgment.
Step 1: Scan the following QR code or search for the keyword “SolaxCloud” in the APP Store to download the Monitoring APP.
Step 2: Click the > button at upper left corner to choose language.
Step 3: Click “Sign Up” at the bottom of Monitoring App.
Step 4: Fill in your registration Email, input the Verification code, and enter your password to create the account.
Note:If the registration fails, please contact the SolaX Technical support team.
Step 1: Log in your account.
Step 2: Allow SolaxCloud to access your system location, fill in site name (self-defined), system size (refers to the total PV power of the system) and add device by scanning the code on Pocket WiFi.
Step 3: Enter your WiFi account and password. Start to configure the device network.
If the WiFi configuration fails, please check the following table to diagnose and seek solutions.
Yes, only one Adapter Box can be connected to the inverter. There will be problems if we connect more than one Adapter Box to an inverter.
It means the rated power of the heat pump.
On-grid, or grid-tied, means the inverter can generate power when connecting to the grid. When the grid is disconnected or cut-off, the on-grid inverters will stop until the grid is back due to anti-islanding requirements.
We have single phase from 600W to 8kW, and three phase from 3kW to 150kW. For more details, please refer to this page: https://www.solaxpower.com/x1-boost
The two modes of Pocket WiFi+LAN both support Modbus-TCP.
How to enable: APP Remote Setting--Network Setting--Pocket WiFi SSID Broadcast. After turning it off, the WiFi signal of the Pocket will be displayed as a hidden network, manually entering the SSID is required when connecting.
In addition to the module support, the inverter's firmware needs to support this feature.
Pocket LAN: W550-xxxxxx
Pocket WiFi 2.0 (SW): MXCHIP
Pocket WiFi 3.0/ Pocket WiFi 2.0 (SX): espressif
Pocket WiFi+LAN and Pocket WiFi+4G: displayed as ‘espressif’, except for 4G (No router for 4G）
Pin 3 and Pin 6 of the RS485_INV can supply the Adapter Box G2 with power.
The Adapter Box G2 automatically assigns a voltage value ranging from 0 to 10 to each step based on the value of the max step. This makes the adapter box g2 suitable for various Analog Input heat pumps.
X3-ULTRA can currently support HS25/36 & HR25/36 & T58 batteries, including two independent battery interfaces:●X3-ULTRA + HS25/HR25, 4~13 batteries per tower (10.0~32.5kWh);●X3-ULTRA + HS36/HR36, with 4~13 batteries per tower(14.7~47.9kWh);●X3-ULTRA + T58, 2~4 batteries per tower(11.5~23.0kWh), with BMS Parallel Box II G2 can connect up to 4 towers;Note: New and old batteries of the same model can be expanded, connecting two ports for different models is not recommended.
IES currently only supports HS50E batteries (5.1 kWh, 102V, stacked batteries);●X1-IES, can be equipped with 1-4 batteries (5.1-20.4 kWh)●X3-IES, available with 2-6 batteries (10.2-30.6 kWh)
X3-IES is available in 6 models: 5 / 6 / 8 / 10 / 12 / 15 kW.
There are two benefits, one is if there is zero export control requirement for your inverter, the inverter still can allow the EVC charger to use surplus solar energy, the other benefit is if your home has energy storage battery installed, the Solax inverter could control the battery not export energy to the charger.
You can also connect an EV Charger and a smart meter.
X3-ULTRA has 6 models: X3-ULT-15K / 19.9K / 20K / 25K / 30K.
Taking the X1/X3 Hybrid G4 series inverter as an example, you need to make the following settings in the inverter: “Advancd”→“Modbus”→"CommFunSelect", select "EVC&AdaptBoxG2.There are two wiring methods: Method 1: Connect the EV Charger to the RS485 port on the Adapter Box G2.Method 2: Use an RJ45 splitter to connect the Adapter Box G2 and EV Charger.
The X1-IES is available in 6 models: 3 / 3.7 / 4.6 / 5 / 6 / 8 kW.
Plug&play, Mobile APP, RFID card.
You can check the system information on SolaX Cloud via Wi-Fi, LAN or 4G dongle. The data includes voltage(U)/Current(I)/Power(Pin and Pout) of PV side and grid side, energy flow diagram, energy of self-use and export to the grid(*meter or CT installation is required) and other detailed info.
