| HM Series NT Microinverter | Residential grid-tied systems using smaller PV modules, with flexible 1-in-1, 2-in-1, and 4-in-1 layouts. | Use DTU-PRO-WIFI for monitoring, plus the HM-compatible AC cable, end cap, port cap, disconnect tool, and connector unlock tool required by the layout. | Choose HM for replacement projects, smaller-module grid-tied systems, or cost-effective module-level PV. |
| HYS Hybrid storage system | DC-coupled solar-plus-storage for new installations; compatible retrofit designs can add storage to existing PV systems. | Pair with a compatible 51.2V battery such as Hoymiles LB-10D-USG2 10.24kWh, plus the DTS-WIFI-G1 gateway and specified CHINT meter. Compatible Deye 48V battery options may also be used where listed. | Choose HYS for a new DC-coupled solar-plus-storage system or a compatible 48V residential storage design. |
| HAS AC-Coupled storage inverter | Existing PV system retrofit projects, including homes that already use microinverters and want to add battery storage. | Pair with compatible 48V LB-10D-USG2 10KWH battery systems. Deye 5.12kWh Rack battery, Deye RW-F10.2-B Outdoor 10kWh battery bank. | Choose HAS for AC-coupled battery backup, an existing-solar retrofit, or a microinverter PV system that needs storage. |
| HMT 2000-4T-NA 208V Microinverter | Small commercial and industrial 208V three-phase PV systems that need 4-input microinverters and lower installation cost. | Use DTU-PRO-S-WIFI, the correct HMT connection cable, HMT cable terminal connector, and HMT trunk connector. | Choose HMT for a 208V commercial microinverter design, four-module inputs, module-level monitoring, or remote O&M through S-Miles Cloud. |
When building an energy storage system with HYS / HAS hybrid inverters, in addition to the inverter and battery, the following accessories are typically required:
These accessories help enable proper communication, energy monitoring, and grid-side power management for the HYS / HAS energy storage system.
To operate an HYS / HAS hybrid inverter, a Hoymiles Power DTS-WIFI-G1 gateway is required.
The DTS-WIFI-G1 connects the inverter to the S-Miles Cloud platform through Wi-Fi, Ethernet, or 4G communication. It is designed specifically for use with energy storage systems, enabling system communication, monitoring, and management.
The DTS-WIFI-G1 is already included with the HYS / HAS inverter, so there is no need to purchase it separately.
In general, microinverters are compatible with most mainstream solar panels on the market. However, it is still important to select the right panel based on the microinverter’s electrical input specifications.
One of the key factors is the maximum input current. The panel’s maximum operating current should generally not exceed the microinverter’s maximum allowable input current. For example, the Hoymiles HMS-2000-4T-NA has a maximum input current of 16A per input, so the selected solar panel should stay within this current limit.
At the same time, very low-power solar panels may not always be suitable. Their operating voltage may be too low to fall within the Hoymiles microinverter’s required MPPT operating voltage range, which could prevent the microinverter from operating properly.
Therefore, when selecting a solar panel for a microinverter, it is important to check both the input current and the operating voltage range, rather than looking only at the panel’s wattage.
An existing microinverter system can add storage through a properly designed AC-coupled system. Hoymiles HAS storage inverters pair with compatible 48V batteries such as the Hoymiles LB-10D-USG2 51.2V 10.24kWh battery. Confirm the final inverter, battery, transfer equipment, and utility design against the applicable manuals and local electrical requirements.
HMS microinverters support newer high-power PV modules, with models designed for module input current up to 16A. HMS and HM series use different AC accessories and DTU monitoring gateways, so every component should be matched to the exact microinverter family.
A typical HMS installation needs one compatible AC trunk-cable connection per microinverter, one port cap and one end cap for each completed trunk-cable run, the appropriate disconnect and connector-unlock tools, and one DTU-PRO-S-WIFI gateway for system monitoring. Confirm cable spacing, conductor size, and branch-circuit limits for the exact model and layout.
No. A standard grid-tied HMS system shuts down during an outage for anti-islanding safety. Backup operation requires a properly designed AC-coupled battery system, transfer equipment, and code-compliant controls.
Both are Hoymiles monitoring gateways. DTU-PRO-S-WIFI is used with HMS series microinverters, while DTU-PRO-WIFI is used with HM series microinverters. Confirm the exact microinverter family before ordering.
Each DTU-PRO-S-WIFI or DTU-PRO-WIFI can monitor up to 99 PV modules in a compatible system. Confirm communication range and gateway compatibility for the selected microinverter family.
Yes, a Hoymiles microinverter system can support zero-export when paired with compatible Hoymiles monitoring and metering equipment, such as the Hoymiles 250A CHINT E-Meter, where the system design and local utility requirements allow it.
