서버 랙 배터리는 무엇입니까??
If you’ve been researching modern energy storage, 특히 태양열 또는 백업 전원의 경우, you’ve likely come across the term "server rack battery." What exactly are they, and why have they become a professional standard for building reliable and scalable energy systems?
A server rack battery is a high-performance lithium battery, typically using the safe and long-lasting 48V LFP (리튬 철 포스페이트) 화학, built in a standardized 19-inch wide format. This design allows the battery modules to be neatly and securely installed ("racked") into a server cabinet. They are the modular building blocks of a space-efficient, 조직, and easily expandable Battery Energy Storage System (베스).
Gycx Solar에서, 우리의 48v 랙 마운트 배터리 solutions are at the core of the advanced energy systems we design. They provide our customers in South Korea and beyond with a powerful, 유연한, and future-proof foundation for their energy independence. Let’s answer some of the most common questions about building a system with these batteries.
How to connect 4 batteries to get 48V?
A common way to build a 48V battery bank in the past was to use smaller, more common batteries. How is this done, and how does it compare to using a modern 48V rack battery module?
To create a 48V system from four individual batteries, you must use four identical 12V batteries and connect them electrically 시리즈로. This means wiring them in a chain: 긍정적 인 (+) terminal of the first battery connects to the negative (-) of the second, 긍정적 인 (+) of the second connects to the negative (-) 세 번째, 등. The total voltage across the remaining open terminals will be 48V.

시리즈로 배터리를 연결하려면 세부 사항에주의를 기울여야합니다:
- The "Identical" 규칙: This is the most critical part. When connecting in series, all four 12V batteries must be identical in chemistry (예를 들어, all LFP or all AGM), amp-hour (아) 용량, 상표, 그리고, ideally, age and manufacturing batch. Using mismatched batteries will cause severe imbalances, leading to poor performance, premature failure of the weaker batteries, and potential safety hazards.
- The Wiring Path: You create a single path for the current to flow through all batteries. The final 48V output is taken from the main positive terminal of the first battery in the chain and the main negative terminal of the last battery.
- The Modern Advantage: This is where a modern 48v 랙 마운트 배터리 module shows its value. A single one of our modules is already a pre-engineered 48V unit.
- 간단: You don’t need to worry about complex series wiring or the risk of mismatched cells.
- 안전: Each 48V module contains its own advanced Battery Management System (비엠에스) that perfectly balances all the internal cells, a task that is much harder in a DIY series string of 12V batteries.
- 확장성: To increase your energy capacity, you simply add another 48V module in parallel, which is a much safer and simpler connection.
While you ~할 수 있다 make a 48V bank from four 12V batteries, using purpose-built 48V modules is the safer, simpler, and more professional approach.
How long will a 48 volt 100Ah battery last?
A 48V 100Ah battery is a very popular size for residential solar storage. It’s a substantial amount of energy, but how long can it actually power your home? The answer depends entirely on your electricity consumption.
ㅏ 48v 100AH 배터리 stores 4,800 와트시 (와트시) 또는 4.8 킬로와트시 (kWh) 에너지의. How long it will last is calculated by dividing this total energy by your electrical load (와트에서). 예를 들어, it could power a continuous 480-watt load for about 10 시간, or a lighter 200-watt load for about 24 시간.
더 깊이 다이빙하십시오: Calculating Your Runtime
Let’s walk through the simple math:
단계 1: Find the Total Energy in Watt-hours (와트시)
- 공식:
Energy (Wh) = Voltage (V) x Capacity (Ah)
- 계산:
48V x 100Ah = 4,800 Wh
(또는 4.8 kWh)
단계 2: Calculate Runtime Based on Your Load
- 공식:
Runtime (Hours) = Total Energy (Wh) / Load (Watts)
Example Scenarios for a Korean Household:
- Essential Loads (대략. 300여): Let’s say during an outage, you’re running your high-efficiency refrigerator, 일부 LED 조명, 인터넷 라우터, and charging your phones.
4,800 Wh / 300 W = 16 hours
- Moderate Loads (대략. 800여): You add a TV and a desktop computer to the essentials.
4,800 Wh / 800 W = 6 hours
- Heavy Load (대략. 2,000여): You decide to run a portable air conditioner or a high-power appliance.
4,800 Wh / 2,000 W = 2.4 hours
This is why our Gycx Solar 48v 랙 마운트 배터리 systems are modular. A 100Ah (4.8kWh) module is a great starting point, but if you need longer runtime, we can easily add a second or third module in parallel to double or triple your capacity.
How many solar panels do you need for a 48V battery?
You have your 48v 배터리 체계; now you need to charge it with solar. How do you size your solar array to ensure your batteries are charged effectively each day?
The number of solar panels needed depends on your battery’s capacity, your location’s climate, and the wattage of the panels. 안정적으로 재충전하기 위해 a 48100AH에서 (4.8 kWh) 배터리 daily in a climate like South Korea’s, with its distinct seasons, you would generally need a solar array of approximately 1.5 kW to 2.5 kW. This translates to about 4 에게 6 현대의, high-efficiency 400W solar panels.
더 깊이 다이빙하십시오: Sizing for a Four-Season Climate
Here’s how we approach sizing a solar array at Gycx Solar:
- Energy to Replenish: We need to put back the energy you use daily. a 4.8 kWh battery using 90% 용량의, 그게 다야 4.3 kWh.
- 피크 일요일 시간 (PSH): This is the key variable. In South Korea, this changes with the seasons. You might get 4.5-5 PSH in the summer, but only 2.5-3 PSH in the winter. We often size the array based on a year-round average or spring/autumn value (예를 들어, 3.5 - 4 PSH) to ensure adequate charging for most of the year.
- 시스템 손실: We account for energy lost from panel heat, 배선, 인버터/충전 컨트롤러 효율성 (typically a 15-25% loss factor).
- 계산:
- 필요한 태양 광 발전 (kW) = 일일 에너지가 필요합니다 (kWh) / (피크 일요일 시간 X 효율 계수)
- 예 (based on a conservative 3.5 PSH):
4.3 kWh / (3.5 hours x 0.80 efficiency) = 1.54 kW (1540 Watts)
- This would mean
1540W / 400W per panel ≈ 4 panels
. To be safe and ensure good charging even on less-than-perfect days, we might recommend 5 또는 6 패널.
GYCX 태양 이야기: "A client in Seoul was concerned about winter charging for their 48V battery system. We designed their array based on the lower winter sun-hour data, ensuring that even on a clear winter day, their batteries would receive a meaningful charge. It’s this kind of climate-specific planning that makes a system reliable year-round."
Can I use 12V solar panels on a 48V system?
You might have access to some standard 12V solar panels and want to use them to charge your new, more efficient 48V battery bank. Is this possible, or are they incompatible?
예, you can use 12V solar panels on a 48V system, but only with the right configuration. 너 must wire the 12V panels in series to increase their combined voltage to a level high enough to charge a 48V battery. 추가적으로, 너 must use a high-quality MPPT (최대 전력점 추적) 태양 전하 컨트롤러, which can efficiently manage the voltage difference between the panels and the battery.
더 깊이 다이빙하십시오: The Keys to Compatibility
Here’s what’s required to make this work:
- Series Connection of Panels: To charge a 48V battery, your solar array needs to produce a significantly higher voltage (typically 60V or more). A single "12V" panel usually has a max power voltage (VMP) of around 18V.
- 그러므로, you need to connect at least four identical 12V panels in series (positive to negative) to achieve a suitable system voltage (4 panels x ~18Vmp = ~72V).
- An MPPT Charge Controller is Essential:
- A cheap PWM (펄스 폭 변조) controller cannot be used. It requires the panel voltage to be very close to the battery voltage.
- an MPPT controller is a sophisticated DC-to-DC converter. It can take the high voltage from your series-wired panels (예를 들어, 72V) and efficiently "step it down" to the correct charging voltage for your 48V battery, capturing the maximum amount of power from your panels in the process.
- The Professional Approach: While using 12V panels is technically possible, modern system designs for 48V batteries usually use higher-voltage panels from the start (예를 들어, "24V" panels or standard 60/72-cell residential panels with a Vmp of 30-40V). Wiring just two of these in series is simpler and often more efficient.
This highlights the importance of system design. Gycx Solar에서, we ensure every component, from the solar panels to the charge controller and the 48v 랙 마운트 배터리, is perfectly matched for optimal safety, 성능, 그리고 효율성.
