Dyness Vs Pylontech Comparison

2021-01-21T04:50:06+00:00

Vs The closest directly comparable energy storage system product to Dyness is Pylontech in terms of modular and expandable system design, and overall flexibility of the system. Pylontech has a growing reputation in Australia as being a very good quality, reliable, and value for money brand, with ever increasing sales volumes. Dyness is a not a very widely known brand around Australia, even though it has been around for about 3 years in the Australian market, and has all the relevant Australian certifications such as CEC approval, and is on the approved equipment lists all the government battery rebate schemes. We have compiled a comparison table to compare the two base 2,4kWh modules from Dyness (B4850) and Pylontech (US2000) on all their technical specs and features. Based on the comparison of all the technical information above, with the exemption of the peak power rate of 2.4kW vs 4.8kW (which is being addressed by Dyness by Q2 2021 to increase peak power to 4.8kW), the Dyness B4850 modules as just as good if not better than the Pylontech US2000 module, and hence provide better value for money. Solar Energy Warehouse is the main importer and distributor of Dyness energy storage systems [...]

Victoria’s Solar Battery Scheme expands statewide and provides 17,500 solar battery rebates over next 3 years

2020-12-02T23:53:48+00:00

On the 17th November 2020, Victoria’s Minister for Solar Homes, Lily D’Ambrosio, announced that the Victorian Government will invest $797 million to support Victorians with their power bills and increase the energy efficiency of their homes, including 17,500 solar battery rebates state wide over the next 3 years. "The Victorian Budget 2020/21 will deliver the biggest household energy efficiency package in any state’s history, creating thousands of jobs, while also reducing greenhouse gas emissions." This will include $335 million to upgrade 250 households with old and inefficient heating appliances such as old wood, electric or gas fired heaters with the latest energy efficient systems that are safer and cheaper to run, which will in turn drive down emissions. Another $112 million will be invested to improve the thermal energy efficiency of social housing properties, which will make homes more comfortable and reduce power bills. $191 million will be spent to expand the existing Solar Homes program to a further 42,000 homes on top of the 100,000 homes who have already benefited by installing solar systems on their rooftops under the program.  This program will also be open to small businesses to apply, offering 15,000 solar rebates for businesses. The Solar Battery Rebate will expanded to cover all of Victoria rather than a specific list [...]

Energy Australia urges federal government to focus on batteries.

2020-12-02T23:54:58+00:00

Energy Australia says that the best way for the federal government to invest in the future of the power market and help economic recovery from COVID-10 is by subsidising battery installations. Head of consumer markets Mark Collette has made calls for a greater focus on accelerating the national transition to renewables to keep up with the recent rooftop solar panels boom by installing household and commercial batteries, to store excess energy created during the day. Prime Minister Scott Morrison’s continued heavy focus on gas as the solution to fill the gap during overcast and windless periods when conditions for renewables are unfavourable has reignited debate about the best path for Australia’s transition, and fuelled concerns from environmentalists and some business leaders who believe stimulus funding would be better spent on expanding clean energy rather than carbon-intensive fossil fuels. Former Prime Minster Malcolm Turnbull said this week that renewable-led economic stimulus would be much more effective than concentrating on gas. Mr Collette said “Solar energy is now quite economic without government subsidy, it’s probably a train that moves without anu support.  I think the case for action around batteries and different support mechanisms that might help on storage could be stronger because it helps some of the emerging challenges across the grid”.

Supporting the Solar Industry

2020-12-03T00:05:39+00:00

There are currently over 2.3 million homes in Australia which have rooftop solar PV systems, and it is projected that there will be at least another million homes to have rooftop solar installed over the next four years. In contrast, there has been a small proportion of homes who have installed battery storage systems with their rooftop solar. Currently, one in eight new solar systems installed included batteries. Industry reports issued in 2017 and 2018 predicted that the uptake of battery systems in Australia would rise in the next few years. Industry forecasts of battery installation by 2020 ranged from 150,000 to 800,000. These predictions have proven to be optimistic, and the reality is probably closer to 70,000 by the end of 2020. It is difficult to obtain accurate battery installation figures because mandatory registration of power systems has only come into effect in early 2020. The main reasons for the lower than expected uptake of batteries are: Batteries have been perceived to be unviable Concerns about safety issues with some older Lithium battery chemistries (pre LiFePo4) Lack of flexibility in battery sizes (ie. Leading brands have limited fixed sizes). Installers have been hesitant to recommend batteries despite an increase in customers interest. With these issues in mind, Solar Energy Warehouse has sourced a [...]

Supporting the Home Building and Property Development Industry

2020-12-03T00:08:25+00:00

There is an increased focus from home buyers on energy efficiency and sustainability features in their homes.  The main drivers for this increased focus could be social awareness, financial benefits, energy independence and more. There is a growing demand from new home buyers in Australia for the new home building industry to offer lower emission homes with lower ongoing energy costs.  This is driving the expectation that new homes built in Australia be designed with high energy efficiency ratings of a minimum of 7 stars.  This 7-star rating would provide the homeowners with at least 3 distinct benefits: They would qualify for a green home loan securing them a 0.4 % discount on their home loan rates from participating banks, for a period of 5 years. The resale value of their homes would attract a 10% premium compared to a comparable house that did not have the same high efficiency rating. Ongoing reduced energy consumption costs. Home builders could become market leaders by offering high efficiency homes that meet the market’s growing expectations.  Home builders could offer 7 star rated versions for their range of homes, or even make all their homes 7 star rated, to gain a competitive advantage in the domestic building industry. There are several ways to achieve a seven-star efficiency [...]

Supporting the Recreational Vehicle Industry

2020-12-03T00:09:23+00:00

There is a growing trend in the Recreational Vehicle (RV) market (ie caravans, motorhomes, campervans & camper trailers) to replace the traditional lead-acid batteries with new lithium batteries (Lithium Ion Phosphate - LiFePO4). There are several reasons for this: Weight Reduction - with the relevant state police forces cracking down on overweight camper trailers, many owners are now looking to strip out weight from their RV vehicles so they are within the legal weight limits by replacing their lead-acid batteries with LiFePO4 lithium RV batteries which are about 25% of the weight and volume of traditional lead-acid batteries, and about 70% of the weight of AGM batteries. This means that by swapping out lead-acid for lithium batteries, the battery capacity can be greatly increased while reducing (or at most equaling) the current volumetric space. These days with ever increasing number of electronic devices installed in modern RVs, this increase in battery capacity is very much needed. High Efficiency - LiFePO4 lithium batteries are generally >95% efficient whereas lead-acid or AGM batteries range between 80% to 85% efficiency. Depth of Discharge (DOD) - LiFePO4 lithium batteries are typically discharged to 80% - 90% on a daily basis and up to 100% in a backup situation without causing any damage, however lead-acid batteries can only be [...]

South Australia’s Home Battery Scheme

2020-12-03T00:10:18+00:00

From October 2018, 40,000 South Australian households can access $100 million in State Government subsidies and $100 million in loans to pay for the installation of home battery systems. While the subsidy is available to all South Australians, Energy Concession Holders are eligible to access a higher subsidy, ensuring low-income households are supported to access the Scheme. The subsidy is applied to the battery component only, participating households can apply for finance made available through the Commonwealth Government’s Clean Energy Finance Corporation to help pay for the balance of the battery and to purchase new or additional solar panels, if required. The subsidy is calculated on the kilowatt hour capacity of the battery being installed, and capped for everyone at a maximum of $6,000 per battery installed. Home Battery Scheme subsidy levels Energy concession holder $600.00 per kilowatt hour (kWh) All other households $500.00 per kilowatt hour (kWh) A set of minimum technical requirements for battery systems has been developed to ensure the batteries are safe, reliable and capable of being recruited into a virtual power plant. While households are able to choose whether or not their home battery system operates as part of a virtual power plant, the ability to aggregate home battery systems - either now or at a future point in [...]
