LG PRIME and SUNGROW SH RT: An Excellent System for PV with Energy Storage

SUNGROW SH RT: A Proven Hybrid for Your Own PV System
The SUNGROW SH RT hybrid inverter is renowned not only for its flexible application and high technical standards but also for its versatility. It supports high-current PV modules and allows up to five hybrids to be connected in parallel, making it ideal for various PV systems ranging from 5 to 15 kWp. Available in four variants with outputs of 5, 6, 8, and 10 kW, it covers both small and medium-sized solar systems. For larger installations, even two SH RT hybrids can be connected. The MPP voltage range of up to 950V ensures that the solar system is optimally managed by the MPP tracker, even at high power levels. Particularly noteworthy is the seamless switch to backup mode in the event of a power outage, guaranteeing uninterrupted power supply—without the need for an additional backup box. The inverter is also compatible with the SUNGROW AC011E-01 charging station, enabling efficient and environmentally friendly charging of electric vehicles.

LG PRIME: High Energy-density Residential Battery
The LG PRIME energy storage system ideally complements the SUNGROW SH RT with its high energy density and powerful charging and discharging rates. With a maximum output of up to 11 kW, even high inrush currents are easily handled, ensuring stable and reliable power supply to your household appliances, even during peak loads. Available in 10 kWh and 16 kWh versions, the PRIME meets all energy needs of a private household. Thanks to advanced cell technology, the LG PRIME achieves particularly high energy density, allowing it to store more energy from the solar system in a relatively small space. No compromises are made when it comes to safety. With over 30 years of experience and renowned premium customers like Mercedes, Apple, and Bosch, LG Energy Solution has proven the safety of its products millions of times.

SH RT + LG PRIME Compatibility
SUNGROW offers the “SH RT” and “SH RT-20” variants of its hybrid inverter. The only difference is the support for high-current modules up to 16 amps in the SH RT-20 version. For most private individuals, these solar modules are irrelevant as they often exceed the allowed base area of max. 2 m² for modules in rooftop systems.

• SH 5.0 – 10 RT: Compatible with LG PRIME 10H / 16H
• SH 5.0 – 10 RT-20: Compatible with LG PRIME 10H / 16H

It is also important to note that a SUNGROW SH RT hybrid inverter should only be connected to the LG PRIME via LG Energy Solution’s 3ph-Box. This small, easy-to-install box merely protects the energy storage system from particularly high voltages, ensuring long-term safe operation.

Planning and Operating a Solar System with LG PRIME and SUNGROW SH RT

Choosing the Right Inverter for Your Roof Size
When planning a solar system, selecting the right inverter is crucial. The SUNGROW SH RT is available in 5.0 and 6.0 versions, which are especially suitable for small single-family and terraced houses with 5 – 9 kWp. The larger 8.0 and 10 versions support PV systems between 10 and 15 kWp. Optionally, two SH RT hybrid inverters can also be connected in parallel, enabling solar systems of up to 30 kWp to be implemented.

Sizing the LG PRIME Storage System
The sizing of the LG PRIME energy storage system depends on the size of the solar system and the electricity consumption. The rule of thumb is 1 kWp of PV capacity for 1.2 kWh of usable storage capacity. For a small solar system up to 9 kWp, the PRIME 10H with nearly 10 kWh would be suitable. For a larger solar system with 10 – 15 kWp, the PRIME 16H with 16 kWh of usable storage capacity is a good match.

Increasing Self-Consumption with the PRIME Storage System
The LG PRIME storage system plays a crucial role in maximizing self-consumption. By storing excess solar energy, it can be used later, reducing energy costs and increasing self-sufficiency. It is essential that the PRIME storage system can cover at least the consumption overnight. Even better is the storage of peak power during midday, which can then be used in the evening, including a reserve for nighttime base consumption.

Monitoring with iSolarCloud
Thanks to full integration into the iSolarCloud monitoring platform, you can keep track of the entire PV system, including the charging station and energy storage. You can monitor production and consumption status in real-time and flexibly adjust settings such as charging and discharging modes. LG PRIME’s open interfaces allow SUNGROW to display as many parameters as possible in their iSolarCloud app. Full insight is available in the RESU Monitor app from LG Energy Solution, where you can find additional details, such as those needed in the event of a service call.

Powered by the PRIME Storage System During Power Outages, Thanks to SH RT’s Integrated Backup

The combination of the SUNGROW SH RT inverter and the LG PRIME energy storage system provides a highly reliable backup solution that activates seamlessly in the event of a power outage. The SUNGROW SH RT inverter automatically switches to battery operation within less than 20 milliseconds, allowing your household appliances to continue running without interruption. The system operates in three phases and is unbalanced load capable, meaning it can easily compensate for uneven load distributions. An additional benefit is that no separate backup box is required, which saves costs and simplifies installation.

Extra Backup Power with the LG PRIME Storage System
The LG PRIME energy storage system plays a crucial role in this setup, as it serves as the energy source for the backup operation. Thanks to its powerful NMC cells, the storage system can briefly operate higher loads in conjunction with the SUNGROW SH RT, providing up to 20% more power for up to five minutes. This allows even more demanding appliances, such as air conditioning units or larger household appliances, to be safely powered in backup mode. If the storage system is fully discharged during a power outage at night, the inverter’s black-start capability ensures that the system automatically recharges and resumes operation at sunrise. This way, your energy supply remains secure, regardless of the conditions.

Cost-Effective Charging of Your Electric Car with the SUNGROW AC011E-01 Charging Station and LG PRIME

The SUNGROW AC011E-01 charging station, combined with the SUNGROW SH RT hybrid inverter and the LG PRIME energy storage system, offers a sophisticated and efficient charging management system for your electric car. With various charging modes, you can charge your vehicle either quickly or particularly economically with PV surplus. The “PV Surplus Charging” mode maximizes self-consumption by automatically switching to increased charging power when excess solar energy is available. Even small surpluses of 1.38 kW are utilized to charge the car, optimizing the use of renewable energy while also reducing energy costs.

Charging Your Electric Car from the LG PRIME
A standout feature is the ability to charge your electric car in the evening, even after the sun has set, using energy from the LG PRIME storage system. When you return home from work, you can charge the car with a few kilowatt-hours from the storage system, without relying on grid power. This is especially useful if immediate mobility is needed or if electricity prices are high. With iSolarCloud, you can monitor and adjust the charging process in real-time, ensuring that your vehicle is always ready—while being as environmentally friendly and cost-effective as possible.

Conclusion

The combination of the SUNGROW SH RT hybrid inverter and the LG PRIME energy storage system offers an outstanding solution for households seeking energy independence and efficiency. With advanced features such as seamless backup operation, intelligent charging infrastructure, and comprehensive monitoring, this system provides everything you need for a future-proof energy supply.
