## A plant matched to your demand

Solis S6-EH3P12K-H combines a PV array, compatible HV battery and three-phase appliances in homes or smaller businesses. Rated 12 kW describes instantaneous conversion capability. Selected battery-system kWh, usable SOC and reserve determine stored energy. Runtime follows actual consumption and simultaneous loads. Batterado helps match modules, storage, metering and electrical equipment.

## Four MPPTs for different roof sections

Four independent trackers connect four strings with up to 20 A input and 30 A short-circuit current per MPPT. Recommended PV array is 24 kWp and maximum usable input 19.2 kW. Start-up voltage is 160 V, working range 200–850 V and full-load range 300–850 V. Design uses actual module currents and string voltage at local minimum temperature within the 1000 V DC maximum.

## Battery: matching voltage, power and capacity

The 120–800 V input serves a compatible high-voltage Li-ion battery with BMS. Maximum current is 50 A and power up to 12 kW according to operating point. Manual references are 120 V at 25 A, 200 V at 50 A and 240 V at 50 A for this model’s full output. Design therefore matches exact battery, module count, voltage, current limits, BMS and firmware. Required kWh follows runtime and demand. Temperature conditions are checked separately for the chosen battery.

## Backup and appliance allocation across phases

Backup output provides rated 12 kW and peak 19.2 kVA for 10 seconds. A single inverter transfers from grid to backup in less than 10 ms. One phase delivers up to 4.8 kW within total output. Dedicated backup circuits use Backup and utility uses Grid. Design considers motor starting, simultaneous appliances and battery capability. Smart loads can be prioritised within a combined Backup plus Smart-load total of 12 kW.

## Seven-inch display and SolisCloud

A large 7″ LCD shows energy flows and operating information on the device. Four keys ESC, UP, DOWN and ENTER complement three LEDs POWER, OPERATION and ALARM. SolisCloud supports local Bluetooth setup with Installer and Owner roles and remote information through included Wi-Fi/LAN. Initial setup covers time, meter, grid code, operating mode and battery model. HMI and app provide corresponding operating data, alarms and system settings.

## Self-consumption, time tariffs and grid charging

Self Use prioritises local consumption and storage; Selling First prioritises export after supplying appliances. Off Grid supports designed independent operation. Six charging and six discharging windows schedule energy. Allow Grid Charging enables recovery at Force Charge SOC or charging when PV is insufficient during a charge window. Adjustable 5–95% SOC reserve keeps energy available for backup. Peak Shaving uses Pmax and target SOC according to system capability.

## Smart port for generator, AC coupling or controlled load

Select the Smart-port role matching the system: Genset input, AC coupled or Smart load output. A three-phase generator up to 12 kW connects at GEN for backup loads or through a designed metered Grid/ATS arrangement. GEN start contact 1/2 is voltage-free; a generator at Grid uses a 5/12 VDC status DI signal on pins 5/6 with the matching external converter. AC coupling integrates a supported three-phase PV inverter up to 12 kW with configured Freq-Watt response. Smart load switches lower-priority demand according to SOC and selected rules.

## Metering and exact battery communications

The offered metering configuration includes Eastron SDM630MCT and three ESCT-TA16 120 A/40 mA CTs. CT arrows point towards grid; standard ratio is 3000 and custom CTs use their actual ratio. Meter RJ45 uses pin 1 A and 2 B, Eastron 14 A and 13 B. BMS CAN is 4 H and 5 L; BMS RS485 uses 3 B and 6 A. Separate external Modbus RTU uses 1 A and 2 B. Dual meters for AC coupling distinguish Grid address 001 and PV inverter 002.

## Expansion and SG Ready heat-pump control

Two to six identical models connect through PAR-B and PAR-A using shielded CAT5 up to 5 m between units. Each inverter has its own battery and BMS; Master address is 1 and other units 2–6. Both DIPs at endpoints terminate the bus according to the original diagram. More than three units use a designed SDM630MCT V2 and ESCT-T50 300 A/5 A metering kit. SG Ready heat pumps use contacts 11/12 for manual or Smart control by SOC and export; default thresholds 90/70% and 2000/−500 W complement minimum runtime 5–60 minutes.

## IP66 mounting and power connections

The 563 ×546 ×250 mm enclosure weighs 35.2 kg, offers IP66 and operates from −25 to +60 °C. Intelligent fan cooling uses 300 mm clearance and 500 mm front service access. Wall-bracket spacing is 289 ×175 mm and vertical mounting allows ±5°. Manual AC Grid conductors are 6–10 mm², Backup/GEN 4–10 mm² and PE 10 mm²; AC terminals and glands use 4–5 Nm. Recommended battery conductor is 8 AWG /8.37 mm². Final cables, protection and earthing follow the actual project.

## Equipment for a complete energy solution

The package includes inverter, backplate, two M4×12 screws, four M10×70 expansion bolts, four pairs of PV connectors, CAN cable, six RJ45s, Bluetooth antenna and quick guide. The offered configuration includes DC switch, Wi-Fi/LAN, 7″ LCD and meter. Selected modules, mounting accessories, compatible HV battery system and electrical equipment complete the plant. The public technical overview, original diagrams and AI search description connect individual specifications to whole-system design.
