Benefits Hybrid Inverter GoodWe ES Uniq GW12K-ES-C10

In the segment of the inverters hybrid single-phase residential, it is common for low voltage equipment to remain in more contained potencies and accept moderate photovoltaic oversizing. The GoodWe GW12K-ES-C10 play in another league: delivery 12kw nominal in a single phase and accept until 24kW FV generator, twice the output power. This allows you to install more solar panels of the usual ones to produce energy also in the first and last hours of the day and on cloudy days, loading the battery while the house consumes.

A 48V high current battery stage

The differential point of the 12KW model is your 240a battery stage in continuous, both in load and unloading. Translated into power, they are 12kW and 13,2kw download: the system can feed full housing from the lithium batteries without resorting to the network, even with demanding simultaneous loads such as aerothermia, induction or recharging of the electric vehicle. Work 48V it is, in addition, a security and cost advantage: low voltage batteries are simpler to manipulate, expand and replace high voltage. The team communicates with the BMS by CAN and it also admits lead-acid, so it fits both in new facilities and in the renewal of systems with aGM batteries or existing gel.

Level back UPS overloading

Before a supply cut, the exit backup commute less than 4ms, a level of level UPS it prevents computers, routers, alarm systems or boilers from being reinstated. The emergency exit is not a limited service line: it offers the 12kva nominal complete and supports peaks 24kva for 10 seconds, sufficient margin for engine start, water pumps or compressors. With present network, the output backup can reach 16,5kva.

Performance and reliability in extreme conditions

With a maximum efficiency of 97.6%, a european efficiency of 96.2% and a MPPT of 99.9%, conversion losses are reduced to a minimum. The wide range MPPT 60 to 550V, with booting alone 58V, allows you to configure short strings and take advantage of low intensity light. Its envelope IP66 and a range of work -35 to +60 ºC until 3,000 m altitude they make it suitable for exterior in any climate of the peninsula. The integrated AFCI protection it detects electric arcs in the direct current wiring, one of the main causes of fire in photovoltaic installations.

Warranty

The manufacturer's technical sheet does not specify the warranty period of this model. Consultation with the team Tienda Solar the warranty conditions in force for the GW12K-ES-C10 before closing your order.

Applications: self-consumption to self-sufficiency

Residential self-consumption with batteries

It is the natural application of the team. During the day, the inverter it prioritizes the consumption of housing, stores surpluses in battery and pour to network only the remaining. At night, the battery covers consumption. Its power 12kw it makes it especially suitable for large single-family homes with high electricity consumption and supply single-phase.

Isolated and generator facilities

The GW12K-ES-C10 works also off-grid and has a aC dedicated entry for generator up 13,2kva. In farms, rural houses or second homeless residences, or with unreliable network, the generator acts as support for recharging batteries when solar production is not enough.

Scalable and micro-network systems

Until 6 inverters can be connected in parallel, both in connection mode and isolated. This allows to grow in a modular way to very higher powers and design systems of micro-network, an interesting solution for small farms, communities or homes that plan to expand their consumption in the future.

Integration in the smart home

Thanks to communication WiFi, LAN, Bluetooth and RS485 and to the protocols Modbus-RTU and Modbus-TCP, the team is integrated with energy and home automation management systems. The app of GoodWe it allows monitoring production, consumption and status of the battery in real time.

How to size an installation with the GoodWe GW12K-ES-C10

Photovoltaic field

With 2 Independent MPPT of 32A each2 strings by MPPT and 16Th Maximum by String), the inverter it allows to work with two different roof orientations, for example east and west. The FV power can reach 24kw, although it is advisable to keep in mind that, with tensions of entry greater than 490V, the loading and unloading power of the battery is limited progressively. For that reason, it is advisable to design the strings to work with clearance below that threshold, with the support of structures for solar panels let them optimize tilt and orientation.

Battery bank

To take advantage of the 240A loading and unloading current, the battery bank must be able to deliver that current continuously. In practice, this usually involves several 48V lithium modules in parallel. The inverter it is compatible with a range of batteries, among them those of itself GoodWe.

Frequently Asked Questions (FAQ)

1. What maximum photovoltaic power can I connect to GoodWe GW12K-ES-C10?

The inverter admits 24kw Power FV, which is equivalent to a overdimensioning of 200% regarding its nominal power of 12kw. The maximum voltage of input is 600V and the MPPT range goes from 60 to 550V, scattered in 2 32A MPPT with two strings each.

2. Is it compatible with high voltage batteries?

No. GW12K-ES-C10 is a inverter of low that works with batteries 48V nominal rank 40 to 60V). It is compatible with batteries lithium (LFP and Lithium Ternario) and of lead-acid, with BMS communication by CAN. If your project requires high voltage batteries, you must opt for another range of inverters hybrid.

3. What happens in my house if the light is going?

The inverter commute to the output backup on less than 4ms, a level of level UPS imperceptible for most electronic equipment. In Isolated mode delivery up 12kva nominal and peaks 24kva for 10 seconds, feeding on batteries and solar panels.

4. Can I install several inverters in parallel to expand power?

Yes. The series ES UNIQ allows you to connect up to 6 inverters in parallel, both in connection mode and in isolated mode, and even operate as micro-network. It is a simple way to scale the system if consumption grows over time.
