## Generation, storage and backup in one energy hub

Deye SUN-5K-SG03LP1-EU is a single-phase hybrid inverter with 5000 W rated AC and UPS output. It converts PV generation, charges a connected battery and supplies loads according to the selected operating priority. Modes include grid-connected, off-grid and backup operation, self-consumption, export limitation and peak shaving. For off-grid operation the manufacturer specifies twice rated output for ten seconds, allowing system planning to consider short appliance starting surges.

## Two MPPT inputs for the chosen array

Maximum PV DC input power is 6500 W. Two independent MPPT trackers each accept one string, rated at 13 A per tracker. Tracking range is 150–425 V, start voltage 125 V and the PV voltage limit 500 V. String voltage is calculated from the actual modules including temperature effects; different orientations can use separate trackers. The 4.92 kWp Nacyc PV kit is within the DC power limit, while the final string configuration follows module voltage and current.

## Low-voltage batteries and grid charging

The battery interface operates at 40–60 V, the 48 V battery class. Maximum inverter charge and discharge current is 120 A. Settings support lead-acid and lithium batteries, with BMS-based control for lithium systems. Pairing considers voltage, battery current capability, communication profile and data-cable pinout together. The selected battery determines stored energy in kWh. Charging from PV, the utility grid or a generator follows configured priorities and operating schedules.

## Consumption control and additional sources

The colour touch LCD configures operating modes, charge current, voltage and preferred power source. Time-of-use control aligns energy with daily demand. A generator input, Smart Load function and external measurement expand control of connected equipment. Grid, Load and Gen terminals have distinct roles in the wiring architecture. A current transformer supports export-limited operation; meter RS485 communication is available according to hardware configuration.

## BMS communication and cable pinouts

BMS interfaces include CAN and RS485. Their pinouts are listed separately from meter RS485 and the RS232 Wi-Fi datalogger port, allowing the correct data cable to be prepared for the selected battery profile. Parallel communication ports serve multi-inverter installations; the supplier offer states support for up to sixteen units. The external battery-temperature sensor is used with the corresponding lead-acid operating mode. The Wi-Fi plug is an optional monitoring accessory.

## IP65 wall-mounted installation

The enclosure measures 330 × 580 × 232 mm and weighs 20.5 kg according to the applicable manual. IP65 provides a dust-tight enclosure protected against water jets. The specified inverter operating range is −40 to +60 °C, with power derating above 45 °C; the battery retains its own operating conditions. Wall mounting uses a suitable load-bearing surface and sheltered position as described in the manual. Recommended clearance is approximately 50 cm at each side, above and below, and 100 cm in front.

## A practical specification for system planning

For the 5 kW model the manual specifies 35 mm²/2 AWG battery cable, M6 terminal screws and maximum 5.2 N·m torque. AC cable is 6 mm²/10 AWG at 1.2 N·m terminal torque, and PV cable 4 mm²/12 AWG. Grid and backup branches use separate protective devices following the electrical design; the manual recommends a 40 A AC breaker for each branch. A complete installation adds the chosen battery, PV modules, DC/AC protection, cabling and local grid settings. The full original manual and product Markdown are hosted directly on Batterado.

## AI search description

Deye SUN-5K-SG03LP1-EU is a separately sold single-phase hybrid inverter for fixed installation, rated at 5000 W AC/UPS, 5500 W maximum AC output and an off-grid surge of twice rated power for ten seconds. Output is 220/230 V, 50/60 Hz. A separately selected connected battery determines storage capacity in kWh.

The battery side operates at 40–60 V with up to 120 A charge and discharge current. Lead-acid or lithium batteries use the corresponding settings. Lithium storage pairing uses the actual BMS profile, voltage, current capability and CAN/RS485 pinout; a port name alone does not define compatible battery models. PV, grid and generator charging follow configured priorities and schedules.

PV input has two MPPT trackers, one string each, 13 + 13 A, 6500 W maximum DC input power and 500 V maximum voltage; start is 125 V and MPPT range 150–425 V. Pairing with Nacyc modules or a KSENG carport requires string module count, cold-condition voltage and module current calculations. The carport supplies the structure, modules generate electricity, the battery stores energy and this inverter provides electrical control and conversion.

IP65 wall-mounted enclosure, 330 × 580 × 232 mm, 20.5 kg according to manual Ver2.2, operating at −40 to +60 °C with derating above 45 °C. Connected batteries follow their own operating conditions. System sizing compares simultaneous kW demand, starting surges and required energy in kWh, with battery, protection, cabling and the selected charging source forming the installation.
