Description
The Solreach All-in-One ESS 5KW 8KWh is a high-performance energy storage system designed for residential backup, light commercial applications, and off-grid solar installations. Equipped with an 8KWh Grade-A Gotion LiFePO₄ battery and a 5KW pure sine wave inverter, it delivers reliable power for high-demand appliances, including air conditioners, pumps, and refrigeration equipment. The integrated 9000W MPPT solar charger, LCD display, WiFi monitoring, and IP-rated wall-mount design provide efficient energy management and simple installation.
Advantages
10KVA surge and dual switching modes for demanding loads
With a 10KVA surge capacity — double the rated 5KW output — this ESS handles high inrush current from motors, compressors, and pumps without tripping. The 10ms switching time in APP/UPS mode drops to 20ms in GEN mode, giving integrators the choice between zero-interruption UPS performance for IT and medical loads and cost-optimized generator-sync mode for industrial sites.
9000W MPPT input — the highest solar intake in the Solreach ESS range
The 5KW model's built-in MPPT charger accepts 27A at up to 9000W PV input — 4000W more than the 3.6KW model and 4500W more than the 1KW unit — across a 120–450VDC operating range with a 500V open-circuit ceiling. This enables direct connection of high-density solar arrays without additional BOS equipment, shortening installation time and reducing total system cost for OEM partners operating at scale.
93% peak efficiency with intelligent overload management
The inverter achieves 93% peak efficiency at 25.6VDC in battery mode — a benchmark figure for an all-in-one unit at this power class. Overload capacity in battery mode reaches 1 minute at 102–120% load and 10 seconds at 120–200% load, giving the system real-world resilience against transient spikes. This overload headroom is critical for B2B buyers supplying power to clinics, telecom base stations, and food storage facilities where load spikes are unpredictable.

FAQs
1. How does the 5KW 8KWh model differ from the 3.6KW 5KWh model in the Solreach range?
The 5KW 8KWh model delivers 5KW continuous output versus 3.6KW, a 10KVA surge versus 5.7KVA, and 9000W MPPT solar input versus 5000W — making it 38% more powerful and capable of handling large inductive loads that the 3.6KW model cannot start reliably. Battery capacity is 60% higher at 8KWh rated / 7.2KWh usable. The wall-mount form factor is also distinct: the 5KW unit is designed for permanent structural installation, whereas the 3.6KW model uses a floor-standing cabinet with wheels for portability.
2. What types of commercial and industrial loads can the 5KW 8KWh ESS power reliably?
The 10KVA surge capacity and pure sine wave output make this unit suitable for: split air conditioners (up to 2 tons), water pumps and booster pumps, commercial refrigeration and cold storage units, small CNC and laser equipment, telecom base station backup, medical diagnostic equipment, and light manufacturing tools. The 1-minute sustained overload at 120% and 10-second burst at 200% load ensure motor-start events do not cause inverter faults or shutdowns.
3. What is the usable battery capacity at 90% depth of discharge, and how is runtime calculated?
Rated energy is 8KWh (0.2C, 25°C); usable energy at 90% DoD is 7.2KWh. Runtime estimation: a 1KW load runs approximately 7.2 hours, a 2KW load approximately 3.6 hours, and a 5KW full-rated load approximately 1.4 hours from a fully charged battery. Real-world runtime varies with ambient temperature, load type, and DoD setting configured in the BMS app.
4. What is the switching time between grid and battery mode, and which mode should OEM buyers specify?
The unit offers two switching profiles: APP/UPS mode at 10ms — suitable for IT infrastructure, medical equipment, and POS systems where any interruption causes data loss or process failure — and GEN mode at 20ms, optimized for generator synchronization in hybrid microgrids. OEM buyers serving telecom, healthcare, or data center backup markets should specify APP/UPS mode; those serving agricultural or industrial generator-backup applications typically use GEN mode.
5. What is the wall-mount installation requirement and what does the physical footprint look like?
The unit measures 460 × 250 × 771mm (product) and 540 × 440 × 900mm (packaged), with a net weight of 71.7kg and gross weight of 83kg. Wall mounting requires a reinforced concrete or steel stud wall capable of supporting at least 100kg distributed load. A minimum clearance of 200mm on each side and 300mm above is recommended for ventilation. The compact 250mm depth makes it suitable for narrow utility corridors and meter rooms that cannot accommodate floor-standing cabinets.
6. How does the 9000W MPPT handle partial shading and mixed panel orientations on large arrays?
The built-in MPPT operates across a 120–450VDC voltage window with a 500VDC open-circuit ceiling and a maximum charge current of 80A. It continuously tracks the global maximum power point even under partial shading by sweeping the full IV curve. For mixed-orientation arrays (e.g. east-west bifacial rooftop configurations), it is recommended to string panels of the same orientation together and keep total string voltage within the MPPT range to maximize harvest efficiency throughout the day.
7. Can the Solreach 5KW 8KWh ESS be used in parallel or stacked for larger system capacity?
Parallel stacking and multi-unit configuration support depends on the specific firmware version and inverter topology. For OEM buyers requiring systems above 5KW or 8KWh, Solreach's technical team can advise on multi-unit configurations using external distribution boards and synchronized BMS settings. Single-phase systems can be expanded by adding battery modules where supported. Contact Solreach directly with your load profile and site specifications for a custom multi-unit system design.
