Balkonkraftwerk Komplettsystem 370W mit HM-300 Mikrowechselrichter

The Solar-Direct Balcony Power Plant Complete Systems from Offgridtec (mpn 014525) are an ideal way to produce a portion of your required household electricity yourself and significantly reduce your overall expenditure on electricity. In addition to a solar module and matching micro-inverter, the systems include everything needed for connection to the household power grid and, if required, for mounting on the balcony railing or roof.

How does a balcony power plant work?

The Offgridtec balcony power plant is a compact Solarasystem. It consists of a solar module and the matching Hoymiles microinverter for feeding into the household power grid. The inverter is ideally attached directly to the substructure of the solar module and connected to the solar module with the solar connector. the ac cable is connected via the Betteri connector of the inverter and led directly to the appropriate socket. Here, there is a choice between connection to the usual Schuko socket or to a Wieland feed-in socket, which is included in the scope of delivery if selected.
In order to use the generated solar power in the house power grid, no special setting is required. If electricity is already available from local sources, the devices in the household use this first and then supplement with mains power if required.

The balcony power plant complete system contains:

• 1x Jinko Tiger 370w solar panel monocrystalline - N-type cells
• 1xHoymiles hm-350 Microinverter
• 1xConnection cable Betteri bc01 socket to Schuko socket(length selectable 5m - 10m - 15m)
• Or 1x Connection cable Betterie b01 female to Wieland RST20I3S-connector(length selectable 5m - 10m - 15m)
• Optional selectable: Mounting package for Balcony railing - Flat roof - Plain tile roof - Tiled roof - Corrugated hernite and sheet metal roof (The sets in question contain 1.25m long profile rails suitable for the balcony power plant)

Jinko Tiger 370w solar module monocrystalline - efficiency of over 21%

Jinko Tiger N-type 60tr (mpn jkm370n-6tl3) is a 370w solar module with monocrystalline cells and N-type technology. The solar cells use multi-busbar technology, with this, the loss due to microcracks has been efficiently reduced, the current transmission path has been reduced by 50%, and the cell efficiency has been improved. The module is manufactured with the Tiling Ribbon process and Hot 2.0 technology.

The Jinko Solarmodule is certified for use in wind and snow loads up to 2400 Pa and 5400 Pa, respectively, and for its high salt and ammonia resistance. The tempered front glass with high light transmission and low iron content has a thickness of 3.2mm and anti-reflective coating. The frame has an anodized aluminum alloy

Hoymiles hm-350 microinverter module inverter

The hm-350 from Hoymiles is the perfect microinverter for your balcony power plant and is suitable for solar power production with a solar panel up to 440 watts peak. Just like all other Hoymiles microinverters, it is suitable for long hours of operation and wide PV panel application, because its commissioning is very low (only 22v) and the DC input range of the operating voltage (16-60V) is extremely wide. The Hoymiles microinverter converts the solar power generated from your photovoltaic system, ac grid compliant and feeds it directly into the utility grid. Each Hoymiles microinverter is individually connected to a PV module of your system for this purpose. This unique configuration means that each PV module is controlled by an individual maximum peak power point tracker (mppt). This ensures that the maximum available power from each individual module is fed into the utility grid, regardless of the output of the other PV modules in the system. Thus, if individual PV modules in the system are affected by shading, soiling, alignment or mismatch, the hm-350 still ensures peak power for its associated PV module. The result is the maximum possible energy production from your PV plant.

• Recommended module power: up to 440W
• Maximum input voltage: 60V
• Maximum input current: 11.5A
• Rated output power: 350VA
• Battery voltage range: 16~60V
• Dimensions (WxHxD): 182 x 164 x 29 mm
• Weight: 1.98kg (including 1.35m ac cable)

Connection set

For the connection cable you have the possibility to choose between the connection for a normal Schuko socket or a Wieland power socket.if you choose this option, the complete system includes an ac extension cable (length selectable) with Betteri bc01 plug, suitable for the hm-350 inverter, at one end and an angled Schuko plug at the other end of the cable. This allows a quick and uncomplicated connection to the Schuko sockets (plug type f) commonly used in Germany.

If the Wieland variant is selected, the ac cable has an angled Wieland RST20I3S plug at the end of the cable for installation in accordance with currently applicable technical regulations (e.g. vde standard ar-n-4105). The appropriate power supply socket is then included in the scope of delivery. With the Wieland plug, the pins are not completely exposed, as with the Schuko plug, which minimizes the risk of arcing between pin and socket and thus overheating and fire hazard.

Optional mounting systems

The Offgridtec balcony power stations are available with or without optional mounting sets. There is a choice of mounting sets for:

• Balcony railings: with matching C-hooks
• Flat roof: angle of inclination 10° - 60°.
• Plain tile roof: with plain tile roof hooks
• Tiled roof: with 3 adjustable roof hooks
• Corrugated hernite and sheet metal roof: with stainless steel hanger bolts

Balcony power plants in Germany

Currently there is no law or regulation in Germany that regulates the generation of solar power for personal use only. The limit of maximum 600w ac PV power is a reserve value that can be fed into an existing socket circuit of a house without overloading it, according to current vde standard. Nothing is described for stand-alone circuits with no additional load.
Any electrical installation should be vde compliant. However, the operation of a balcony power plant via the usual Schuko socket is not prohibited in principle. Notification to the Federal Network Agency is mandatory. However, there are no known cases of administrative fines for non-notification of balcony power plants, as well as insurmountable problems with network operators. The compliance and implementation of standards and obligations is the responsibility of the plant operator. A lot of technical and legal information can already be found on relevant websites.
