随着物联网和全家自动化的进步,令人惊讶的是,方程式不包括在储能系统中容易管理。当房主挂起电池时,通常只有几个电路被重新连接以备份。卧室的灯可能无法获得紧急电源,但至少冰箱和空调仍在运行。
这往往是安装公司的最大教育障碍 - 解释说市场上的锂电池实际上无法提供全家备份。摩根·布劳纳(Morgan Brawner),业务发展副总裁必威体育app苹果手机版SunPower by esaSolar说,这次谈话通常是具有挑战性的the Central Florida installer. Many customers are interested in storage for hurricane-induced grid outages, and they believe one Tesla Powerwall will provide power for the whole home.
他说:“储能不是可以快速添加为订单物品并忘记的商品。”“这需要进行一些真实的对话,以说明您可以用一个电池电量电源。当我们完成工程包时,我们会使用“最终配置”文档,我们的客户签名清楚地说明了我们正在备份的哪些电路,以确保安装当天没有任何惊喜。”
New generation electrical panels and smart circuits can change that conversation. Instead of only backing up a few loads through a protected loads panel, smart circuits and energy management software allow for load toggling — someone can stop supporting the air conditioner for a little while to instead turn on some lights.
选择或自动化哪些电路用能量存储支持的能力是硬件/软件组合的主要卖点Lumin. A physical box installed next to a home’s electrical panel, Lumin allows for whole-home backup (on varying schedules) by making all circuits smart. Through an app, system owners can manage their energy usage and protect their batteries from prematurely running out of juice.
Esasolar by SunPower已将Lumin安装在其电池项目的大约四分之一中,并期望随着存储市场的不断增长,该数字将会攀升。Brawner将Lumin描述为房主的“游戏规则改变者”,以更好地将监视体验与实时使用行为联系起来。Lumin不仅可以监视电池,还可以实际管理使用。
他说:“我认为,光伏和能源存储的未来将涉及智能能源管理方面的更多创新,以更好地透明能源行为趋势和家庭能源利用。”
Lumin于2016年推出,是一种通过改进久经考验的断路器面板的技术来提高绿色能源的一种方式。公司联合创始人和CCO Kevin O’Shea表示,Lumin并没有用全新的配置代替房屋的Breaker面板,而是与任何电池品牌和电气面板一起使用的简单附加组件。
“entir取代现有的断路器面板ely new one is very costly in terms of time and labor before you even add on the cost of the product itself,” he said. “Our approach allows us to meet the market demand for smart and responsive load control without that large upfront cost.”
Another product in the nascent smart circuit market is Span’s electrical panel. Unlike Lumin, theSpan Smart Panel取代传统的断路器面板,成为房屋的主要能量和控制枢纽。SPAN没有兼顾两个盒子的维护,而是使所有电路都聪明。
SPAN于2019年在精选市场推出,为32台电路提供了智能定制。当电源熄灭时,SPAN智能面板会隔离房屋,并允许客户通过智能手机应用程序控制重要负载。SPAN由特斯拉,亚马逊和Sunrun之前由高管和工程师领导,与LG Chem和Panasonic建立了关系,电池公司提供的跨度作为包装交易。该小组目前在加利福尼亚和夏威夷可用,新市场即将推出。
“Self-sufficiency and control within the home are top of mind for many homeowners with power outage concerns now compounded by coronavirus shelter-in-place orders,” said Span founder and CEO Arch Rao in a press release. “Last fall, power outages affected millions in California, and shutoffs are starting again as utilities perform precautionary maintenance in fire-risk areas. We developed the Span smart panel to give homeowners greater energy independence in the face of these growing challenges. With Span, they have greater control over their home energy, especially when they need it most.”
While it’s true that battery companies offer monitoring through their own apps, they don’t give the user any control. A smart circuit setup can monitor charging levels while also providing load control. O’Shea said the Lumin system remains on “watch mode” to automatically govern loads. It makes sure the home’s microgrid doesn’t prematurely run out of backup power or exceed the battery’s output rating — something that many end-users don’t give a second thought.
“Imagine driving a car without a fuel gauge. What’s more, the car starts driving itself whenever the power goes out, regardless of how much gas is in the tank,” O’Shea said. “You just spent [upwards of] $20,000 on a battery backup system to make sure the car doesn’t run out of gas. It really isn’t acceptable to leave it up to chance whether or not that car runs out of gas, especially given that it starts itself and runs automatically when the power goes out.”
O’Shea said it’s the responsibility of energy management technology like Lumin’s to protect customers from “running out of gas” unexpectedly or too quickly.
Lumin和SPAN都符合UL的能源管理设备标准(UL 916),而SPAN也将UL 67作为常规电池板传递。这些智能电路公司的下一个障碍是采用更广泛的市场。Esasolar的Brawner认为这只是时间问题。
“For PV monitoring, homeowners want to see insights on if their system is producing power and if there are any issues. After a few months, it becomes like watching paint dry. For storage, the monitoring applications are very much the same,” Brawner said. “That is the problem that Lumin solves. For a homeowner, the Lumin is providing real-time engaging information to bridge the gap between technical monitoring and home energy use.”
我为太阳能光伏系统安装了一些电池。电池系统电源=约6.5kW,能量= 20kWh。有什么原因我不能只把所有房屋电路都放在备用面板上?我意识到我会受到限制,但没有一个高功率负载,除了交流电会自动打开。当网格降低时,我只需要记住决定打开另一个负载时运行的负载即可。换句话说,为什么我什至需要一个备用面板?不能只是手动限制中断期间施加的负载吗?
Span? Or Lumin? that is the question.
我知道这是从去年开始的,但是我的电池备用计划与我们的太阳能电池板相连,并且想知道是否有人可以建议我们。有人告诉我们,我们的交流完全无法在电池上运行,因为它在60安培电路上。我阅读的所有内容(包括本文)都提到了使用交流电各种时间的时间,但根本不能表明它们根本无法使用。我的交流是否超大了电池?这只是一个普通大小的房屋的常规交流电,该房屋本来应该是节能的,大约在10年前由Lennox制造。但是似乎没有电池可以处理它。在中断中使用AC是我们首先考虑备份电池的主要原因。任何人都将不胜感激。
启动交流电单元所需的放大器(功率)必须超过电池电网下降时电池所能产生的。这要么是电池的限制,要么是逆变器。您的交流单元具有一个标语牌,指示锁定的转子放大器(“ LRA”)才能启动它。您的电池和逆变器必须能够在短时间内生产该金额以使系统运行。Sometimes you can install an after-market “soft start” device, like Hyper Engineering’s “Sure Start,” that can dramatically lower the starting amps required to turn on your AC unit…and allow your battery and inverter to meet the power requirements to start it when you are in backup mode. Note, it is not the “60A Circuit” rating (Circuit Breaker), but the LRA rating of the AC unit that matters. Finally, sometimes adding another or a larger battery will allow you to output enough “surge” current to start the AC unit…but that depends on your system. Good luck. Hope this helps or was at least informative.
The technology around solar-systems and renewable power production can be mind-boggling for a layman like me. I have built a 6kw solar-array that includes microinverters (for simplicity sakes) approximately 500ft from my house. The feed-line ties directly into the grid at the power pole which is connected to the dwelling in the opposite direction. The system works fine, but to this day I have no back-up in case of a power failure. I simply haven’t found an electrical contractor who could tell me what automatic isolation device on the market would be suitable for my application. This is of course a rural setup which doesn’t apply to towns and cities where the grid is connected directly to the house, I would assume. Unfortunately, none of this promising technology can be applied in my case, until the mandatory isolation requirement has been solved.
The direct grid tied mentioned is an Achilles heel of your system. Micro inverters like (Enphase) do have a ‘system’ that can island and support some critical circuits in your house during a power outage. You’d have to take the grid connection off of the power pole and into a secondary Circuit Breaker panel, with a break before make automatic transfer switch, between the secondary and primary C.B. panels.
Technology has changed so much in the last 5 years. The Smart ESS is probably the best (value) at a higher cost than the old simple series wired panel strings, paralleled into the “house inverter” then out into the grid through the house C.B. panel. It is possible to use the smart ESS intrinsic grid interactive inverter as a programmable house inverter or off grid back up inverter.
每当有一种新技术用于太阳能或新的机架或跟踪与非移动架子(作为太阳能电池板系统承包商)时,我总是有一个很大的学习曲线可以适应。而且,我的电气承包商和安装人员也这样做。由于电气承包商和安装人员都不总是很了解,因此问题总是落在我的肩膀上。然后,我通常最终没有在第一份工作中做任何事情。那个客户感到不高兴,因为他/她认为我是个笨蛋。另外,试图让我的潜在客户了解更改通常几乎是不可能的。而且,新产品制造商通常不会将其产品规格表放入以外的任何人都可以轻松理解的形式。所有这些都非常令人沮丧。我们的行业适应新环境真是太好了。但是进度通常比预期的要慢。
感谢您所做的一切!感谢您没有从事紧急工作,并实际花时间了解您正在安装的内容。
“新一代电气板和智能电路可以改变对话。智能电路和能源管理软件不仅可以通过受保护的负载面板来备份一些负载,还可以使负载切换 - 有人可以停止支撑空调一会儿来打开一些灯。”
Sonnen Ecolinx可以做到这一点,并且刚刚发布了Ecolinx 30.0 ESS,如果需要的话,可以使用20%的紧急情况。在德国,Sonnen从一开始就为交互式网格设计,具有获取天气数据并确定要存储多少能量的能力,现在要使用多少能量。使用智能家用电器,Sonnen可以与特定的电器进行通信,并且可以通过智能手机上的应用程序控制房屋中的负载。Generac刚刚宣布与一家正在执行智能能源控制和VPP的公司建立合作伙伴关系。
“选择或自动化哪些电路用储能支持的能力是Lumin硬件/软件组合的主要卖点。Lumin旁边安装了一个物理盒,Lumin允许通过使所有电路聪明地进行全家备份(在不同的时间表上)。通过应用程序,系统所有者可以管理其能源使用情况,并保护其电池免受过早用尽果汁的影响。”
We have been institutionalized in the “brute force” method of power to one’s home. You take a 200 Amp circuit breaker panel times the 240VAC buss structure and you get roughly 48,000 watts continuous. The reality is surge accommodation is around 48,000 watts maximum, but the actual load on the home’s C.B. panel at any one time may be 80 to 125 Amps maximum. The smarter the system, the more loads can be powered. Go to your electric panel now and look closely at it. On top is the house Main rated at (100), (200) Amps, then count and add up all physical circuit breakers in the panel. I’m pretty sure you’ll find if you loaded every plug in the house, turned on all appliances, lights, ceiling fans and the A/C unit(s) and water heater, you’d probably trip the house breaker every time. In this day and age many air conditioning units have a power fail wait timer, so when the utility restores power, the large surge of the A/C unit is not immediate and usually 5 minutes of continuous power is needed before the A/C is allowed to restart. Many of the Energy Star devices from washers, cooktops, refrigerators/freezers and air conditioning units are now using variable frequency drives, these electronically controlled motors have power surges from 40 to 50% less of an old across the line motor of the past.
I don’t believe the sonnen ecoLinx supports ALL circuits like the devices mentioned in this story. Still need a protected loads panel for the chosen circuits.
Thanks for that.
I was able to get up close and personal to a model home with a actually small solar PV array, maybe 2.5 to 3kWp on the roof and a sonnen ecolinx 20.0 in each garage. The development is by Mandalay in Arizona. The Sonnen was “locked” so I couldn’t scroll through the programming pages and menus. But the sales pitch was upgrade your energy efficiency package and you could “talk” to your smart home appliances, set the shades in the windows and turn on and set the air conditioning from a smart phone app, I believe these particular Sonnen units have an internet gateway that can communicate to the house appliances. When all is said and done, the smart interactive inverter is the way to go. Early on before Schneider bought out Xantrex, the XW6048 way back in 2008 was able to be programmed utility interactive and one could actually program in how much energy to sell to the utility and the rest was stored and used on site. With battery technology, and a little larger smart inverter one could run a home off of solar PV most of the time and use the utility as backup.
Just wanted to chime in and say it’s great to see the XW6048 getting some love I’m off-grid and have been running off that unit for 12 years and it’s fantastic (I had an eaaaarly model and needed to self-replace a circuit-board but otherwise it’s been trouble-free for all these years). Don’t tell my solar friends this but we’re finally looking to add some grid power source and might finally unlock this feature.
这是有关Generac的一些信息。他们没有智能的电气面板,但是可以管理负载。
Generac的Pwrcell系统的工作方式不同。该端到端系统利用天然负载管理技术更聪明地工作并提供全板备份功率。发生停机时,Pwrcell自动传输开关破坏了与网格的连接,Pwrcell逆变器将备份功率引向主面板。同时,如果本地需求超过系统的备份容量(使用单个PWRCELL电池,Generac Smart Management模块(SMMS)将暂停低优先级负载(最高9kW)。当需求减少并提供功率时,SMM可以允许较低的优先级负载再次运行。如果需要,SMM也可以直接散开电路。最多可以通过SMM控制八个电路,该电路可以在任何方便的位置上线连接,从而减少了改装智能面板或子面板的劳动。此外,PWRCELL ATS最多可以控制四个恒温器,以优雅的方式减轻大型HVAC负载。
谢谢,这清除了一个可以“岛屿”关键家乡电路的系统的混乱。
The industrial controls industry as a whole usually have an (HMI) human machine interface, which many are in and of themselves self contained Computers with display screens in one unit. Tag based programming in these HMIs one can create many custom control programs for power flow in differing situations. Digital inputs from the on board ATS could be used to physically signal the system to switch into stand alone mode and island critical circuits in one’s home.
