Anker SOLIX Solarbank 2 E1600 Pro - Balcony Solar Storage With 1600Wh And 2400W PV Input

Anker SOLIX Solarbank 2 E1600 Pro is a compact all-in-one battery and microinverter system designed to sit under residential solar panels and store up to 1600Wh of energy while feeding up to 800W back into the home grid from a balcony or small rooftop installation. With a stackable LiFePO4 battery architecture and integrated controls, it targets households that want to capture more of their self-produced solar power instead of letting midday generation go unused.

Battery Capacity And Core Hardware Specs

At the heart of Anker SOLIX Solarbank 2 E1600 Pro is a LiFePO4 battery pack with a rated storage capacity of 1600Wh in the base unit, giving enough energy to buffer typical balcony solar output across several hours of consumption.Manufacturer data for the Solarbank 2 E1600 Pro lists 1600Wh capacity, LiFePO4 chemistry and a 15 year product lifespan with 10 year warranty. The same data sheet specifies the battery type as LiFePO4, a lithium iron phosphate chemistry known for around 6000 charge cycles before capacity drops to about 70%, which aligns with third-party reviews that highlight its long expected life for daily cycling.One independent test notes approximately 6000 cycles to 70% capacity and a 10 year warranty. In daily operation, that cycle depth is designed to support many years of regular charging and discharging as the system tracks solar production and household load.

The integrated power electronics give the Solarbank 2 E1600 Pro its dual role as both storage and grid-feed device. Anker specifies an on-grid AC output of 800W, which is the maximum continuous power the unit can feed back through the connected AC port into the home's electrical circuit during normal operation.Support documentation lists on-grid AC output at 800W and off-grid AC output up to 1000W, along with a 16-60V DC operation voltage range for the PV inputs. In addition to the grid-feed port, the unit offers an off-grid AC output rated up to 1000W, intended for emergency use or to power devices directly from the battery when the grid is down, with some configurations able to reach 1200W off-grid with expansion batteries according to distributor data.A specialist retailer lists on-grid AC output at 800W and off-grid output up to 1000W, increasing to around 1200W with expansion batteries.

Physically, the Solarbank 2 E1600 Pro is built as a squat rectangular unit designed to sit beneath or beside balcony PV modules. Manufacturer specifications give dimensions of 460 x 249 x 254mm and a weight of 21.8kg, meaning roughly a half-meter length, quarter-meter width and height with a mass that generally requires two people for safe handling.Anker lists the Solarbank 2 E1600 Pro at 460 x 249 x 254mm and 21.8kg. The housing carries an IP65 rating, indicating dust-tight construction and protection against low-pressure water jets from any direction, an important factor for installations exposed to rain on balconies or exterior walls.Retailer specifications show IP65 weatherproofing and a temperature range from ?20 °C to +55 °C for outdoor use.

PV Connectivity, MPPT System And Smart Control

A key distinguishing feature of Anker SOLIX Solarbank 2 E1600 Pro versus many compact microinverter batteries is the number and capacity of its maximum power point tracking inputs. The unit offers four MPPT channels, each rated up to 600W, for a total maximum PV input of 2400W, allowing connection of several high-output panels while optimizing energy harvest individually per string.Support documentation lists four MPPTs with up to 600W per channel and a combined max MPPT input power of 2400W. Each MPPT accepts currents up to 16A with a short-circuit current limit around 20A, and operates within a 16-60V DC range, which matches the typical voltage window of modern residential PV modules.

This multi-channel MPPT layout is intended to accommodate up to four panels, commonly around 540W each in European test setups, where Anker has highlighted the capability to produce roughly 2324kWh per year from four 540W solar modules under ideal conditions.The manufacturer notes that four 540W panels feeding the Solarbank 2 can theoretically generate about 2324kWh per year. While that annual figure reflects a specific climate and irradiance assumption, it illustrates the device's ability to handle sizeable balcony or small rooftop arrays that would otherwise dump surplus production to the grid at low feed-in rates.

On the control side, the Solarbank 2 E1600 Pro integrates Wi-Fi and Bluetooth for connection to Anker's app ecosystem, enabling remote monitoring of real-time solar input, battery state of charge and grid-feed output. Manufacturer data references both Bluetooth and 2.4GHz Wi-Fi connectivity alongside smart-meter-based dynamic load management, where an optional Anker Smart Meter measures household consumption and directs the Solarbank to throttle or increase its output within its 800W on-grid limit.A detailed review notes 4 MPPTs, Wi-Fi and Bluetooth, dynamic output via an Anker smart meter and time schedule-based control through the app. In practice, that means the unit can be programmed with schedules or operated in auto modes to prioritize self-consumption during peak household usage and avoid pushing power back to the grid when tariffs are unfavorable.

Scalability, Expansion Batteries And Emergency Use

Although the base Solarbank 2 E1600 Pro carries 1600Wh of storage, the design is explicitly stackable: additional expansion battery modules can be physically stacked and electrically connected on top of the main unit to increase total capacity. Distributor information and independent tests describe expansion battery modules of 1600Wh each, with up to five expansion units supported, resulting in a total capacity up to 9600Wh when all slots are filled.A German test reports that the 1.6kWh base battery is expandable up to 9.6kWh via five 1.6kWh stackable expansion modules. Another retailer listing notes that with certain BP2700 expansion batteries the system can be extended further to around 15100Wh of total storage, using five higher-capacity modules.Distributor specs indicate 1600Wh base capacity, expandable to 9600Wh with five BP1600 batteries or 15100Wh with five BP2700 batteries.

This stackability is central to the Solarbank's role in small residential setups. A single 1600Wh unit may be enough for apartments with moderate evening consumption, but multi-unit stacks allow larger households to capture more midday solar and run appliances longer from stored energy. Tests comparing Solarbank 2 Pro to competing devices highlight the benefit of being able to extend capacity without replacing the inverter or rewiring the entire system, which stands in contrast to some all-in-one devices that do not support modular scaling.A comparison matrix notes that Solarbank 2 Pro supports expandable capacity and can act as a limited power station with a 1000W socket, while some alternatives lack such expansion or off-grid output. For power outages, the off-grid AC output, rated around 1000W on the base system and up to 1200W with certain expansion batteries, provides enough power to run essentials such as lighting, networking equipment and smaller kitchen devices, though not heavy loads like full-size electric ranges.

Positioning, Pricing And Market Context

In European markets where the Solarbank 2 E1600 Pro has been widely tested, Anker initially set an MSRP around 1199 euros, with some later retailer pricing around 591 euros depending on promotions and bundle offers.A review lists an MSRP of 1199 euros and a retailer price around 591 euros for the Solarbank 2 Pro in its test. For US readers, these figures primarily serve as a reference for positioning: the device sits in the mid-to-upper range of small residential storage packs in terms of cost, reflecting its integrated inverter, four MPPT channels and long-cycle LiFePO4 battery. Where comparable balcony systems might offer 1200W PV input and non-expandable storage, Solarbank 2 E1600 Pro pairs 2400W PV input with modular batteries, a 10 year warranty and IP65 housing, which aligns it closer to fully featured home energy storage kits than simple plug-in microinverters.

Compared with some alternative balcony storage systems noted in test comparisons, Solarbank 2 Pro typically offers higher PV input capacity and longer battery life estimates. For instance, one competing all-in-one unit is listed with 2400Wh battery capacity but without expansion capability and with a shorter lifespan around 3000 cycles, while Solarbank 2's 1600Wh base capacity can be expanded and is rated for roughly 6000 cycles to 70% capacity.A comparison shows Solarbank 2 Pro at 1600Wh expandable, 6000 cycles and 2400W solar input, while a Zendure unit has 2400Wh fixed capacity, lower cycle endurance and no expansion. For households planning multi-year use, such cycle life differences translate into practical longevity, especially under daily cycling regimes where batteries may reach several thousand cycles over their operational life.

Use Cases And Who It Suits

Functionally, Anker SOLIX Solarbank 2 E1600 Pro is best suited to households or apartment dwellers with limited roof space but access to balconies or small flat roofs where two to four solar panels can be mounted. With its 2400W PV input across four MPPTs, it can capture significant midday production from high-efficiency panels and store it in the 1600Wh base battery or extended stacks up to 9600Wh or 15100Wh depending on expansion modules.A series overview places Solarbank 2 Pro at 1600Wh capacity with four MPPTs at a maximum of 2400W and emergency output up to 1000W, compared with Solarbank 2 Plus at 1600Wh with two MPPTs and 1200W total. The IP65 rating and ?20 °C to +55 °C operating temperature window allow installation in regions with cold winters and hot summers, making it broadly applicable within temperate and many continental climates.

Limitations primarily revolve around peak power and regulatory constraints. The 800W on-grid AC output cap means that even if the PV array is generating 2400W, the device will modulate its feed-in and battery charging so as not to exceed the rated grid output, which is typically aligned with balcony power regulations in European markets. For US readers, local codes and utility interconnection rules would shape how such a system can be deployed, particularly around plug-in connections and export limits. Its off-grid output ceiling around 1000-1200W also means it will not replace whole-home backup systems rated in multiple kilowatts, but it remains suitable for smaller loads during outages.
