Sungrow SH-RL: SH5RL, SH6RL, SH8RL and SH10RL Hybrid Inverters with SBL060 Battery

The Sungrow SH5RL, SH6RL, SH8RL and SH10RL hybrid inverters belong to the SH-RL series, designed for residential photovoltaic installations combining solar self-consumption, low-voltage energy storage and backup power during grid outages.

With rated outputs of 5, 6, 8 and 10 kW, this series stands out for its flexible configuration, compatibility with high-current PV modules and integration with the Sungrow SBL060 6 kWh battery.

In this article, we examine the technical specifications of each model and their applications in residential solar PV system design.

Sungrow SH-RL: Hybrid Inverters for Solar Self-Consumption and Energy Storage

The Sungrow SH-RL series includes four single-phase hybrid inverters designed to manage PV generation, battery charging and discharging, and residential electricity supply.

A key feature is its low-voltage battery architecture, supporting a battery operating range of 40 to 60 V.

The SH5RL and SH6RL models feature two independent MPPTs, while the SH8RL and SH10RL offer three MPPTs for greater system design flexibility.

Key technical features include:

• 20 A per MPPT: compatibility with high-current PV modules, within the electrical limits of each input.
• 40–425 V MPPT range: flexibility when designing PV strings.
• Backup function: switching time of ≤4 ms under typical conditions.
• Backup peak power: up to 200% of rated power for 10 seconds, subject to system limitations.
• AFCI protection: electric arc fault detection.
• PID Zero technology: mitigation of potential-induced degradation.
• iSolarCloud monitoring: access to system operating data.
• IP65 protection rating: equipment protection under the manufacturer’s specified installation conditions.

Sungrow SH5RL and SH6RL: 5 kW and 6 kW Hybrid Inverters

The Sungrow SH5RL and SH6RL are designed for single-phase residential installations combining solar self-consumption, energy storage and backup power. Both incorporate two independent MPPTs, with a maximum input current of 20 A per MPPT and one PV string per tracker.

SH5RL and SH6RL Technical Specifications

Both models use natural convection cooling and have a typical maximum noise level of 35 dB(A). Their dimensions are 532 × 386 × 210 mm, with a weight below 19 kg.

When Should You Choose the SH5RL or SH6RL?

The SH5RL is suitable when 5 kW of rated power meets the installation requirements. The SH6RL offers greater conversion capacity and supports higher recommended PV input power. Selection should consider household consumption, PV array configuration, grid connection capacity and storage requirements.

Sungrow SH8RL and SH10RL: 8 kW and 10 kW Hybrid Inverters

The SH8RL and SH10RL are designed for residential installations with higher energy requirements. Their main difference from the 5 and 6 kW models is the inclusion of three independent MPPTs, enabling the management of three PV strings and different roof orientations.

SH8RL and SH10RL Technical Specifications

Both models feature fan cooling, dimensions of 552 × 448 × 250 mm and a weight below 27 kg.

When Should You Choose the SH8RL or SH10RL?

These models can suit projects with higher electricity demand or PV arrays requiring three MPPT trackers. The SH10RL supports up to 20 kWp of recommended PV input power, with a maximum usable PV input power of 16 kWp.

Sungrow SH5RL, SH6RL, SH8RL and SH10RL Comparison

The main differences between these four inverters are rated power, number of MPPT trackers and battery charging and discharging limits.

Sungrow SBL060 Battery: 6 kWh Low-Voltage Energy Storage

The Sungrow SBL060 is a low-voltage lithium iron phosphate (LiFePO4) battery designed for integration with Sungrow SH-RL hybrid inverters.

It provides 6 kWh of nominal energy and 5.8 kWh of usable energy, with a nominal voltage of 51.2 V.

Its modular design allows storage configurations of up to 24 kWh nominal capacity using four batteries connected in parallel per inverter.

The integrated BMS monitors operating conditions and the relevant electrical and thermal protections.

Sungrow SBL060 Technical Specifications

An integrated BMS monitors battery operation and provides protection against electrical or thermal conditions outside the permitted limits.

How Many SBL060 Batteries Can Be Connected?

Up to four SBL060 units can be connected in parallel per inverter, providing a maximum nominal capacity of 24 kWh.

Backup Function: Power Supply During Grid Outages

The SH-RL series can supply the loads connected to the backup circuit during a grid outage, provided that the system is correctly configured and sufficient energy is available.

The specified switching time is ≤4 ms under typical conditions. The inverters can also deliver peak power of up to twice their rated power for 10 seconds, under applicable operating conditions.

Maximum Continuous Backup Power

The actual power available depends on the inverter, the battery state of charge and specifications, and the connected loads. The switching time alone does not guarantee uninterrupted operation for every sensitive electronic device.

Smart Monitoring with Sungrow iSolarCloud and iHomeManager

SH-RL inverters support monitoring through iSolarCloud, Sungrow’s platform for viewing solar generation, inverter operation and battery status.

Integration with Sungrow iHomeManager enables selected smart load management functions and compatible devices. The technical documentation also covers integration options for generators and microinverters, subject to the necessary accessories and technical conditions.

Safety Features and Protection Systems of the Sungrow SH-RL Series

The SBL060 battery also features a C5-M corrosion resistance classification stated in its technical documentation.
