With stackable architecture, compatibility across leading inverter brands, and 8,000-cycle longevity, LG RESU16H Prime solar battery delivers tier-one reliability for households transitioning from grid dependence to true energy autonomy.

  • Modular Configuration
  • Flexible Inverter Pairing
  • Scalable to 32 kWh

About the Product

The LG RESU16H Prime solar battery combines advanced lithium ion NMC technology with intelligent battery management for residential and light commercial installations. Engineered with dual battery modules and a dedicated control unit, this solar battery enables professional installers to optimize placement in tight spaces. 

Unlike single-enclosure competitors, this split design distributes 351 pounds across three manageable components for easier handling during installation. Each 16kWh module delivers 7kW continuous power with 11kW peak surge capability, maintaining critical loads during grid outages. Installation flexibility extends to climate extremes. Natural convection cooling eliminates mechanical fans, removing a common failure point while enabling silent operation in living spaces.

Operating within a 350-450V DC range, the RESU16H Prime solar battery integrates with high-voltage string inverters. The onboard DC-DC converter achieves over 90% round-trip efficiency, minimizing conversion losses during charge-discharge cycles.

LG's 10-year warranty covers both manufacturing defects and capacity degradation, guaranteeing 70% retention after 54MWh of energy throughput—equivalent to 3,375 full discharge cycles. The parallel expansion option future-proofs installations, allowing homeowners to double capacity to 32kWh without replacing existing equipment or rewiring inverter connections.

    FAQs

    Are your products organic / natural?

    Our products combine the power of naturally occurring and advanced science ingredients that are simple to use, highly effective, non-toxic, non-irritating, and absolutely cruelty-free. We do not use aggressive, irritating ingredients. Beyond this, we do not like labels such as ‘organic,’ ‘natural’ or ‘clean,’ which have no consistent definition and tell you nothing about a product’s safety or efficacy. We are committed to bringing you the very best ingredient science and being certified “organic” does not always yield the best ingredient.

    Do your products contain fragrance?

    Generally not, but with limited exceptions. “Fragrance,” when used in our products like the ANTI-AGING BODY CREAM, is selected for its pleasant scent but also for its proven tolerability. Most fragrances contain allergic substances, or “allergens”: if present, it is compulsory to state this on the label, even if the percentage contained is minimal. Where possible, we tend to use fragrances which do not contain allergens and which should therefore give rise to fewer problems. When fragrance is present in a our product, is indicated in the list of ingredients as PARFUM or FRAGRANCE.

    Is there talc in any of your products?

    The minerals that are used to produce talc can contain asbestos, which is why there are legitimate concerns about its potential effect on our health. The talc used in our ENZYME CLEANSER, BABY BUM CREAM and tinted CLARIFYING SPOT TREATMENTS is NOT made of minerals that contain asbestos and thus is not carcinogenic and completely safe. The talc we use is periodically and consistently reviewed by independent laboratories.

    What is the shelf life of my product?

    All beauty products need to be used by a certain period. This is known as the 'period after opening' and can be easily identified by the PAO symbol. The symbol can be recognised as the shape of an opened jar, and will have a number inside; 9M will indicate 9 months, 12M is 12 months, and 36M is 36 months. Once opened the product should be used in this period, as after this time the quality of the product will deteriorate.
