PV, storage and backup in one system
Solis S6-EH3P12K-H-EU(21A) connects PV, a compatible high-voltage battery and three-phase loads. Rated 12 kW describes instantaneous power; selected battery kWh, usable SOC and consumption determine stored energy and runtime. Batterado matches modules, battery, metering and electrical equipment for homes or smaller businesses.
Independent trackers for PV design
Four independent MPPTs connect four strings, each up to 21 A input and 31.5 A short-circuit current. Recommended array is 24 kWp and maximum usable PV input 19.2 kW. Start-up is 160 V, MPPT range 200–850 V and full-load range 250–850 V. Each tracker accepts up to 9000 W input. Design accounts for actual module currents and cold string voltage within the 1000 V maximum.
HV battery matched to energy and power
The 120–700 V battery input works with a compatible Li-ion system and BMS. Maximum charge and discharge current is 50 A, with up to 12 kW according to actual voltage and BMS limits. Design selects exact model, module count, voltage, firmware and communication settings. Battery capacity is selected separately in kWh. PV-to-battery efficiency reaches 98.31%. The chosen battery has its own operating-temperature specifications.
Backup circuit and load allocation
Backup output delivers rated 12 kW and briefly 19.2 kVA for 60 seconds. Transfer takes less than 10 ms. A single unit supports 100% imbalance and up to 6 kW on one phase within total output. Dedicated loads connect to Backup and utility to Grid. Design accounts for simultaneous appliances, starting peaks and battery capability.
Scheduling and grid charging
Self Use prioritises local generation use, Feed-in Priority configured export, Off Grid independent operation and Peak Shaving battery assistance at grid Pmax. Six charge and six discharge windows schedule energy. Allow Grid Charging enables charging during selected times or SOC recovery. Adjustable backup reserve keeps selected energy available. Default over-discharge SOC is 20% and force-charge SOC 10%.
Metering for energy-flow control
The offer includes a meter and Wi-Fi/LAN monitoring. Standard metering uses Eastron SDM630MCT and three ESCT-TA16 120 A/40 mA CTs with arrows towards grid. Meter RJ45 pin 1 A and 2 B connect to Eastron 14 A and 13 B; the supplied cable is 5 m. More than three parallel units use the matching SDM630MCT V2 and ESCT-T50 300 A/5 A kit according to the manual.
Bluetooth, app and communications
SolisCloud provides local Bluetooth configuration and remote information through included Wi-Fi/LAN. Installer and Owner roles expose corresponding settings and operating data. Commissioning sets time, battery, meter, grid code and mode. Five LEDs show Battery, Power, WiFi, RS485 and Bluetooth. BMS CAN uses pins 4 H and 5 L with a 3 m cable; separate external Modbus RTU uses RS485 pin 5 A and 4 B. The current manual also describes a generator at Grid through ATS, a 12 VDC status signal and a 220 VAC/12 VDC converter. App settings select generator source, charging and charge power; default charge SOC is 25–80%. DI/DO 5 and 7 control a supported heat pump manually or in Smart mode using SOC and export. Defaults enable at 90% SOC and 2000 W export, disable at 70% or −500 W. Minimum runtime is adjustable 5–60 minutes.
Expansion with two to six identical units
A parallel system connects two to six identical inverter models through P-B and P-A using recommended shielded CAT5 up to 5 m between units. Each inverter uses its own battery and BMS connection. Primary address is 1, others 2–6; configure unit count and Parallel Sync. Grid side uses a balanced three-phase design. Bus endpoint termination follows the selected original manual diagram.
IP66 and natural cooling
The IP66 enclosure operates from −25 to +60 °C with natural convection. Dimensions are 563 ×412 ×230 mm and weight 34.5 kg. Vertical wall mounting allows ±5°, bracket spacing 515 ×170 mm and 200 mm clearance for airflow and access. Location and supporting structure suit actual weight and installation conditions. Manufacturer noise rating is below 46.9 dB(A).
Connections for the designed plant
PV uses 4–6 mm² conductors, recommended 4 mm²; battery 10 mm² and manual AC specification 2.5–6 mm² with cable diameter 14–17 mm. Grid and Backup have separate quick connectors. AC terminal torque is 0.8±0.1 Nm, nut 2.5±0.5 Nm and M4 earth 2 Nm. Final design adds suitable protection and earthing. The family supports optional AFCI 2.0 and DC/AC Type II SPD versions according to selected equipment. The offered price configuration includes both DC and AC Type II surge protection and AFCI 1.0.
Equipment and complete-system selection
The package includes inverter, backplate, four M4×12 screws, cover, Bluetooth antenna, meter with three CTs, meter cable, CAN cable, six RJ45s, Grid/Backup/BAT connectors and 4 pairs of PV connectors. Offered configuration adds Wi-Fi/LAN monitoring. A complete plant uses selected modules, mounting accessories, matching HV battery and electrical equipment. Batterado connects kW output with required kWh energy and actual appliance use.
