Product Information
Specifications
- Product Name : [Product Name]
- Model Number : [Model Number]
- Battery Voltage Range : DC26-60V (for 36V/48V batteries) or DC45-90V (for 60V/72V batteries)
Product Usage Instructions
Panel Connection
The first step is to connect the battery. Ensure that the positive and negative electrodes of the machine are correctly connected to the positive and negative electrodes of the battery. Then, connect the inverter to the home power grid.
Battery Voltage Selection
For the DC26-60V version, only 36V/48V batteries should be used to power the inverter. For the DC45-90V version, only 60V/72V batteries should be used.
Connection Methods
Comparing the connection methods shown in Figures 4 and 5, it is recommended to use Method 2. However, Method 1 may be chosen due to its thicker DC cable, which results in a higher price. Method 1 requires three pairs of parallel connectors and three pairs of MC4 connectors for connection. On the other hand, when using Method 2, a very thin DC cable is used, requiring only a pair of parallel connectors and a pair of MC4 connectors for connection.
Step-by-Step Connection Instructions:
Method 1:
- Connect the positive electrode of the machine to the positive electrode of the battery using a parallel connector.
- Connect the negative electrode of the machine to the negative electrode of the battery using a parallel connector.
- Connect the positive and negative terminals of the battery to the inverter.
- Connect the inverter to the home power grid using the appropriate connectors.
Method 2:
- Connect the positive electrode of the machine to the positive electrode of the battery using a parallel connector.
- Connect the negative electrode of the machine to the negative electrode of the battery using a parallel connector.
- Connect the positive and negative terminals of the battery to the inverter.
- Connect the inverter to the home power grid using the appropriate connectors.

This inverter can be connected to solar panels or batteries separately.
Panel connection
The first step is to connect the solar panel, pay attention to the positive and negative electrodes of the panel to be correctly connected to the positive and negative electrodes of the machine, and then connect the home power grid in the second step.
Solar panel voltage selection:
SUN-1000GTIL2-M : The 22-65V inverter will start at 26V, and the inverter
can work at 22V-60V after starting. Solar panel Voc cannot be higher than 60V.
Solar panel open circuit voltage Voc38-60V is recommended.
SUN-1000GTIL2-H/SUN-2000W-H: DC input of grid-connected inverter 45-90V (starting voltage 49V). Solar panel Voc cannot be higher than 90V. Suitable for open circuit voltage 76-90V (Voc)
Battery connection
The first step is to connect the battery. Note that the positive and negative electrodes of the machine should be correctly connected to the positive and negative electrodes of the battery, and then connected to the home power grid.
Battery voltage selection
- DC26-60V version : Only 36V/48V batteries are used to power the inverter.
- DC45-90V version : Power the inverter with only 60V/72V batteries.
- Note : When using a battery to power the inverter, use a circuit breaker. Select the correct type of solar grid inverter. Because there may be several ways to connect solar panels to sunlight
For grid-connected inverters, different connection methods may require different models of inverters. In this case, there are two connection methods.
Using method 1, since all panels are connected in parallel, we can know The TVoc (Total Voc of a Solar Panel) will be the same as the Voc of a Solar Panel, and TVMP It’s the same Vmp as a particular panel, so we can get the specs of the solar.
The solar panel arrays are interconnected.
- TPmax: 245W × 4 TVMP: 29.4V
- TImp : 8.34A × 4 TVoc: 36.9V
- TIsc : 8.68A × 4
From these specifications, we should use SUN-1000G-M. because of the DC input voltage The voltage range of this model is 22V to 65V, so the TVoc and TVmp are at the DC input voltage Scope.
- With Method 2, we can also obtain the specifications of the solar panel array.
- TPmax : 245W × 4 TVMP: 29.4V × 2
- TImp : 8.34A × 2 TVoc: 36.9V × 2
- TIsc : 8.68A × 2
- From these specifications, we should use SUN-1000G-H. Because of the DC input voltage
- The voltage range of this model is 45V to 90V, so the TVoc and TVmp are at the DC input voltage Scope.
-
Comparing the connection methods in Figures 4 and 5, we can see that Method 2 is a good method. Method 1 is chosen because the DC cable is thicker, so the price is more expensive, and three pairs of parallel connectors plus three pairs of MC4 connectors are used. However, when using Method 2, the DC cable is very thin, only a pair of parallel connectors is required, and a pair of MC4 connectors should be used for connection.

Install a larger capacity grid-connected power system. Sometimes, you may be willing to install a larger capacity grid-connected inverter in your home House, this is also very easy to operate. For example, if you want to install a 2KW grid-connected power system, you can install two 1KW grid-connected power systems, as shown in Figure 5. The two AC output cables should all be plugged into the AC sockets of the utility grid. This
The diagram of a 2KW grid-connected system and two 1KW systems is shown in Figure 6, and we call the type system a “stackable system”. -
You only need one SUN-2000G2 2KW inverter to replace two SUN-1000G2 1KW inverters, and connect about 2KW of solar panels to the inverter to get 2KW of “SGPV”. You can also install multiple “SGPVs” in parallel to get a large grid-connected system.
