In brief
What the Hoymiles
HIT Series is
The Hoymiles HIT Series is a range of three-phase hybrid inverters for low-voltage batteries in the voltage range from 40 to 60 V. One unit connects the PV array, battery, grid and, if required, a generator, and keeps supplying the connected loads on all three phases during a grid outage.
Hoymiles manufactures the range in eight power classes from 5 to 20 kW, each with LED ring (G3) or color display (G3S). PVSelected stocks five models in its B2B shop: HIT-6L-G3S and HIT-8L-G3S with color display as well as HIT-10L-G3, HIT-15L-G3 and HIT-20L-G3 with LED ring. They are complemented by the batteries LB-6D-G3 (6.02 kWh), LB-16D-G3 (16.08 kWh) and the stackable battery LB-5S-G2 (5.12 kWh).
PVSelected supplies the range to installers in Germany, Austria, Switzerland and the Netherlands. Warehouse: Halskestraße 3-5, 47877 Willich.

Why this range
Six reasons that
count on site
Several roof areas on one unit, backup power for the entire distribution board, reserve for starting currents and a unit that can be mounted outdoors. Six arguments to help you sell the HIT.
01 · PV input
Several roof areas, one unit
The larger classes have four MPP trackers, each with 20 A input current and 30 A short-circuit current. Each roof area gets its own tracker and is optimized separately: shading or a different orientation on one area does not affect the output of the other trackers. DC/AC oversizing of up to 200 % is permitted.
MPP trackers per class: HIT-6L-G3S 2, HIT-8L-G3S 3, HIT-10L-G3 3*, HIT-15L-G3 and HIT-20L-G3 4 each. MPP voltage range 150 to 900 V, start-up from 150 V. According to the manufacturer, the low start-up voltage adds about half an hour of generation time.
20 AInput current per MPP tracker
02 · Backup power
Backup power for the entire distribution board
In on-grid mode, the backup loads run through the integrated bypass with up to 50 A continuous current. If the grid fails, the HIT disconnects from the grid and keeps supplying the loads on the EPS output on all three phases, including the entire house distribution board if it is connected there. In backup mode, 100 % unbalanced load is permitted, up to 50 % of the rated power per phase, so single-phase loads keep running as well.
According to the G3 datasheet, the switchover time is below 10 ms. The manufacturer's documents state different values, so we plan for 10 ms max.
50 ABypass continuous current in on-grid mode
03 · Starting reserve
Reserve for heat pumps and motors
In backup mode, the HIT provides twice its rated power for ten seconds, up to 40,000 VA with the HIT-20L-G3, provided PV and battery supply enough power. This reserve is intended for the starting currents of heat pumps, pumps or compressors. Whether it is sufficient depends on the starting current of the load and on the battery: an LB-16D-G3 delivers up to 240 A for 10 seconds, an LB-6D-G3 up to 90 A.
Without PV, at night for example, the battery limits the peak. Calculated value: one LB-16D-G3 alone 240 A × 51.2 V, approx. 12.3 kW for 10 s; the HIT-20L-G3's battery limit of 350 A corresponds to approx. 17.9 kW. The system brochure also states twice the power for 10 s in off-grid operation.
2 ×rated power for 10 seconds, depending on PV and battery
04 · Energy sources
PV, battery, grid and generator
The HIT manages four energy sources: PV, battery, grid and generator. Instead of a generator, the GEN port can also supply loads and control their power consumption. The energy management integrates generator, heat pump and controllable loads, and up to ten inverters can operate in parallel, both on-grid and off-grid.
Interfaces according to the Quick Installation Guide: heat pump via analog signal or SG Ready, charging station and external control via RS485, external emergency stop.
4Energy sources on one unit
05 · Tariffs
Charge when power is cheap
In addition to self-consumption and peak shaving, the HIT handles time-of-use tariffs: up to eight schedules of 24 hours each define when the battery charges and when it supplies the house. With tariffs that have fixed time windows, the battery charges during low-cost hours and supplies the house during expensive ones.
Hoymiles states up to 8 % higher revenue through tariff control, a manufacturer's figure with no test conditions stated.

- Battery supplies the house
06 · Outdoor installation
Can be mounted on an outside wall
The inverter is rated IP66 and operates from -25 to +65 °C, with derating from 45 °C. The Quick Installation Guide permits outdoor wall mounting exposed to sun, rain and snow. The LB-G3 batteries can be installed indoors or outdoors, rated IP65, with self-heating for -20 to 55 °C.
According to the manufacturer, the LB-S-G2 stackable battery is rated IP66 and operates from -10 to 45 °C.

How much power does the HIT deliver in backup mode?
Up to the rated power of the respective class, i.e. 6, 8, 10, 15 or 20 kW, provided PV and battery can deliver this power. Without PV, the battery current is the limit: an LB-6D-G3 delivers 60 A continuously, calculated at approx. 3.1 kW at 51.2 V. For 10 seconds, the HIT provides twice its rated power, 40,000 VA with the HIT-20L-G3, again only with sufficient PV and battery power. In on-grid mode, the bypass carries up to 50 A to the backup loads. In backup mode, 100 % unbalanced load is permitted, up to 50 % of the rated power per phase.
Which model suits which PV power?
The decisive factor is the recommended maximum PV power according to the datasheet: 12 kW for the HIT-6L-G3S, 16 kW for the HIT-8L-G3S, 20 kW for the HIT-10L-G3, 30 kW for the HIT-15L-G3 and 40 kW for the HIT-20L-G3. This corresponds to oversizing of 200 %. Each MPP tracker accepts up to 20 A; the smaller classes have 2 and 3 trackers, HIT-15L-G3 and HIT-20L-G3 have 4 each. For the HIT-10L-G3 we plan for 3 trackers; the G3 V1.0 datasheet states 4, and we are clarifying this with Hoymiles.
Which battery fits, and how far can it be expanded?
In the shop we offer the LB-6D-G3 with 6.02 kWh and 60 A continuous current, the LB-16D-G3 with 16.08 kWh and 160 A, and the stackable battery LB-5S-G2 with 5.12 kWh per pack. The LB-G3 batteries are individual units for wall, floor or wheeled installation and are connected electrically in parallel, up to 16 units; the calculated capacity is 96.32 kWh with LB-6D-G3 and 257.28 kWh with LB-16D-G3. According to the manufacturer, the G2 range covers 5.12 to 102.4 kWh, with up to 4 packs per stack (calculated value from the type designation LB-(5-20)S-G2). The choice depends on capacity, the required battery current and the weight at the installation site: 55 kg for the LB-6D-G3, 115 kg for the LB-16D-G3.
Can I combine old and new battery modules?
For LB-6D-G3 and LB-10D-G3, Hoymiles allows mixing old and new modules; an integrated DC/DC converter balances the states of charge. According to the manufacturer, this function does not apply to the LB-16D-G3. Hoymiles does not describe combining G2 and G3 batteries, so please check this with us in advance.
How quickly does the HIT switch to backup power?
The manufacturer's documents state values between 0 and 10 ms, depending on the document. Please plan for 10 ms max.; if required, we will agree a binding value for your project with Hoymiles.
Can the HIT be installed outdoors?
Yes. The inverter is rated IP66 and operates from -25 to +65 °C, with derating from 45 °C. The Quick Installation Guide permits outdoor wall mounting exposed to sun, rain and snow. Clearances of 500 mm to the top, bottom and sides and 1,000 mm to the front must be maintained. The LB-G3 batteries are rated IP65 and heat themselves in cold conditions, operating range -20 to 55 °C.
Which batteries can I connect?
The datasheet lists lithium-ion and lead-acid batteries in the voltage range from 40 to 60 V. Lithium batteries communicate with the inverter via CAN, and charging follows the BMS; lead-acid batteries are charged in three stages with an equalization charge. For new systems, we recommend the Hoymiles batteries from the shop, because monitoring and your point of contact then come from a single source.
What is the GEN port for?
A generator can be connected to the GEN port as a fourth energy source alongside PV, battery and grid. Alternatively, the port supplies loads and controls their power consumption. Via the COM2 interface, the HIT also controls heat pumps via analog signal or SG Ready and can control a generator.
How do I monitor the system?
Via the Hoymiles S-Miles Cloud, as an app and in the web portal: energy flows, power curve, remote diagnostics. The connection is established by the data stick: with G3 via WLAN, LAN (only with the DTS-WL-G3 stick) or 4G, with G3S via WLAN, Ethernet or 4G. Commissioning is done in the Hoymiles app via QR code.
What is the difference between G3 and G3S?
The G3S models have a color display, the G3 models an LED ring. The G3S datasheet lists more grid connection standards, including TOR Erzeuger Typ A for Austria. Within the same power class, the electrical characteristics are largely identical; the exceptions are the number of MPPTs in the 10 kW class and the switchover time specification. In the shop, the 6 and 8 kW classes are G3S, the 10, 15 and 20 kW classes G3.
Which standards does the HIT meet?
The datasheets of all five shop models list VDE-AR-N 4105 and EN 50549, plus IEC 62109 for safety. TOR Erzeuger Typ A is only listed in the datasheet of the G3S models. A datasheet listing does not replace a unit certificate: we compile the documentation for the grid operator for your registration and request anything missing from Hoymiles.
Technical assessment
Where the HIT is
the right approach
Where the range has its strengths, where it reaches its limits and what this means for system sizing.
Low voltage instead of high voltage
The HIT works with batteries between 40 and 60 V; the LB-G3 batteries have a rated voltage of 51.2 V. This means the modules can be placed individually and expanded in parallel, up to 16 units. The trade-off is high currents: up to 350 A on the HIT-20L-G3, battery cables up to 150 mm². So plan cable routes and cross-sections before installation. Other Hoymiles solutions: the HiOne and the HiBattery.
When the range pays off
The five shop models cover 6 to 20 kW, from single-family homes to small businesses. Oversizing of up to 200 % and up to four MPP trackers help with east-west roofs and multiple roof areas. The range is at its strongest where backup power for the entire house distribution board is needed or a generator is to be integrated, for example on farms.
Limits you should know
The inverter is approved for wall mounting only; floor and wheeled installation refer to the batteries. The battery current is often limited by the battery: an LB-6D-G3 delivers 60 A continuously, the HIT-20L-G3 could handle 350 A. This also applies to the backup peak without PV. Battery cables need up to 150 mm², and we define the fusing together with you. TOR Erzeuger Typ A is only listed in the datasheet of the G3S models.
What PVSelected contributes
