Il dissipatore di calore è ben dimensionato e non necessita di ventole visti i rendimenti dichiarati dalla casa che credo siano corretti anche sulla base dei test che ho fatto. Inoltre il modello 20A gestisce potenze tutto sommato modeste ( 480w con batterie da 24v). Il display è a cristalli liquidi senza retroilluminazione con tutti i problemi dei cristalli liquidi. Di giorno e con vista frontale sono nitidi e chiari, con vista disallineato non si riescono a leggere. Non è che uno sta sempre lì a guardare il display, una volta impostato si controlla ogni tanto. Con l'app questi problemi non ci dovrebbero essere, però occorre comprare un ammennicolo wifi da aggiungere. La morsettiere fa il suo lavoro ma forse si poteva fare meglio. La programmazione è un po' macchinosa visto che si deve entrare nei vari menù, scorrerli fino al parametro di interesse, modificarlo e salvarlo. Vero che si fa una volta sola, ma è un po' noioso. Sul display di possono vedere tensioni e correnti gestire dall'apparecchio ma mancano statistiche più accurate, credo che sempre con app e ammennicolo il problema si risolva Cosi come la programmazione. Per me l'apparecchio va bene visto anche il costo di acquisto scontato ed è certamente completo per l'uso stand alone. Al prezzo di vendita pieno , senza sconti, si trovano apparecchi più completi con wifi app incluse. Review: 独立型の50W太陽光パネルで使っていたPWMチャージコントローラーが壊れたので、その代替として急遽購入しました。 PWMコントローラーは50Wシステムを構築するテストみたいな感じで安いのを買ったのですが、十分使えていたのでどっちにするか悩んだのですが、今は50Wパネルを本格的に運用していますし「MPPTで効率を上げるのはこのタイミングかなー」って思ってこちらにしました。 しばらく運用してみたところ、発電量が多い時はそれほど変わらない働きですがMPPTの本領を発揮する「薄曇り、もしくは斜めから日が当たる状況」で随分と差が出ます。 PWMでは余り発電しない状況でもMPPTだと結構発電していて、やっぱりMPPTは強いなと思いました。 MPPTと書かれていても、あまり安いものは偽物である可能性が高いので、評価がある程度定まっているものを高くても買おうと思ってこちらにしたのですが、それが正解でした。 長い期間使うものですから、少し値が張っても確実なものが一番です。 ## Features - Innovative MPPT Design Die-cast aluminium design ensuring excellent heat dissipation and Renogy Maximum Power Point Tracking technology with a high tracking efficiency of up to 99% and peak conversion efficiency of 98%. It is the best charging solution even in cloudy environments where the max power point of the solar panels will fluctuate all day. - 12V/24V Automatically Detect Automatically detects 12V or 24V DC system voltages (for Non-Lithium battery types), and the LCD screen and multiple LED indicators display the solar charging and battery operation information, customizable parameters, and error codes. - Full System Protection Meant to safeguard your system, the self-diagnostic capability can s and protect anst reverse polarity, battery overcharging, battery over-discharging, overload, short-circuiting, and reverse current. - 4-Stage Safely Charging Features 4-stage charging (Bulk, Absorption, Float, and Equalization) of Lead Acid Batteries and 2-stage charging (Bulk and Absorption) for Lithiuim batteries as well as Lithium Reactivation - Diverse Load Control Connect DC appliances directly to the optional Load Terminals and monitor consumption or set up timer controls directly from the controller.Remote Monitoring The RS232 communication port allows the Renogy Rover charge controller to communicate with the DC Home app and Renogy ONE M1 via the Renogy BT-1 Bluetooth module (highly recommend to add-on ). This will enable you to monitor the status and productivity of your panels on the go. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MRWTAB5 | | Brand Name | Renogy | | Color | black | | Customer Reviews | 4.4 4.4 out of 5 stars (1,200) | | Display Type | LCD | | Global Trade Identification Number | 00816360024644 | | Included Components | Rover Li 20 Amp MPPT Charge Controller | | Item Dimensions L x W x H | 21L x 15.1W x 5.9H centimeters | | Item Type Name | 20A MPPT Charge Controller 12V/24V Auto DC Input Solar Charge Controller, Parameter Adjustable, LCD Display Solar Panel Regulator, fit for Gel Sealed Flooded and Lithium Battery, Rover 20A | | Item Weight | 680 Grams | | Manufacturer | Renogy | | Material Type | Plastic | | Operating Temperature | 45 Degrees Celsius | | UPC | 816360024644 | | Unit Count | 1 Count | | Voltage | 24 Volts | ## Product Details - **Brand:** Renogy - **Colour:** black - **Material:** Plastic - **Product dimensions:** 21L x 15.1W x 5.9H centimeters - **Voltage:** 24 Volts ## Images ![Rover 40 Amp 12V/24V DC Input MPPTSolar Charge Controller - Image 1](https://m.media-amazon.com/images/I/51kxTqa5WwL.jpg) ## Questions & Answers **Q: Is anyone having problems with hf / vhf radio interference (rfi)?** A: On MPPT and PMI controllers of different brands, RFI particularly in the VHF & UHF bands can be extreme. The solar panels do act as large antennas transmitting the interference. Some fairly simple decoupling circuitry can help. Right at the PV input, i've used a large forward diode into a large, CPU-grade electrolytic along with common-mode chokes on wiring before the diode. On the controller outputs, a "Corcom" type pi-filter helps a lot, but components in series with the output must accept full output current without much voltage drop. This can get rid of about 99% of RFI without too much problem. I do use solar and wind turbines for power at my off-grid property and run amateur radio equipment from 70 cm to 160 meter bands. **Q: What does "rated battery current" mean? Does the load current change with each different model?** A: The rated current is 20Apeak If you want to connect to inverter that draw more than 20amp Use relay to switch load Connect relay coil to Rover load output **Q: What is the max available amps to the load terminals?** A: I never put loads directly on the controller. I only put loads on the battery terminals. **Q: I have a: itehil solar panel, 100w 18v monocrystalline portable solar panel, high efficiency waterproof solar panel. can i use it with this controler?** A: Sure, but get a Victron instead. This is an antique. 😉 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***M on 13 September 2024* Robusto ben fatto, completo di tutte le funzioni indispensabili per un mppt stand alone.

Er kommt in einer tollen Verpackung, sogar ein Temperatur Sensor ist dabei, den man beispielsweise an seine Batterie kleben kann. Mein Testaufbau bestand aus zwei 100w Panelen mit 12v. Bei schlechter Sonneneinstrahlung lieferte der Regler stabile 7A Richtung Batterie. Das finde ich beeindruckend, da mein alter PWM Regler im selben Setup nur 4,5 schaffte. Bedienungsanleitung ist auch dabei, hatte ich nicht nötig da der Regler automatisch die richtige Batterieart erkannt hatte. Preislich ist er auch absolut Fair!
