- 99% trackingtechnologie: de Litime 30A MPPT zonne-laadregelaar met geavanceerde Maximum Power Point Tracking technologie kan continu het maximale vermogenspunt van de array volgen om de maximale hoeveelheid energie voor het opladen van de batterij te behouden. De tracking-efficiëntie bedraagt niet minder dan 99% en de piek-conversie-efficiëntie bedraagt tot 98%.
- Bluetooth-functie: de Litime 12 V/24 V MPPT-controller is uitgerust met een RS232/bluetooth-communicatie om de bluetooth-adapter met RJ12-poort (meegeleverd) te verbinden, wat de gebruiker in staat stelt om de real-time status van het zonnepaneel, de batterij en de lasten op afstand te bewaken.
- Hogere prestaties: max. Zonnepaneel ingangsvermogen: 450W voor 12V/900W voor 24V; Max. Ingangsspanning zonne-energie: 100 V.
- LCD-scherm en led-displays: de Litime MPPT-controller is uitgerust met een lcd-scherm voor de weergave van de systeembedrijfsinformatie en 4 knoppen voor bediening in de menu's. Bovendien helpen meerdere led-indicatoren om de toestand van het zonnepaneel, de batterij, de lasten en de regelaar weer te geven.
- Uitstekende warmteafvoer en meerdere beschermingsfuncties: de Litime MPPT-controller is gemaakt van gegoten aluminium, wat een uitstekende warmteafvoer garandeert om het vermogensverlies te verminderen. Bovendien kunnen de meervoudige beveiligingen die in de zonne-laadregelaar zijn ingebouwd, ervoor zorgen dat de regelaar volledig beschermd is tegen omkering van de verbinding, overstroom, overspanning, kortsluiting en te hoge temperatuur.
- Extra componenten: de in de accessoires meegeleverde koperen draadconnector kan het contactoppervlak tussen de draad en de MPPT tijdens de installatie vergroten, wat het vermogen tot stroomoverdracht verhoogt.

Good to have if you've never seen the iTEP exam, but don't rely on it to boost your scores
Format: Paperback
This book is good in that it comes with two practice tests: one in the beginning of the book, one in the end of the book. The grading rubric is helpful too. However, the actual guide part of the book, doesn't help too much with how to improve test scores. What I like least about this guide is that it won't tell you which questions you answered incorrectly on the practice exams. A good test prep guide will tell you what you answered incorrectly, and will tell you what logic to follow to get to the correct answer. In the reading passages, it would be nice to know where I can find evidence to justify the "correct" answer. In the grammar section, it would be nice to know which rule I'm violating. Any test guide should always come with some testing strategies. I.E. If this question is taking up too much time, skip it and go to the next one. This guide lacks simple strategies like that. Simple strategies like that could be useful when incorporated into this guide because there are certain sections on the exam that you can go back to previous questions, but some sections where the "back" button is disabled.
Overall, if you've never seen an iTEP exam before, this book is certainly helpful in that it will give you an idea of what you will be testing for. However, this book alone won't help you achieve a score of 6. The table of contents itself will tell you there are only 86 pages of actual content covering test material. That's not enough to cover how to excel in the exam.

Don't buy it
Format: Paperback
It does not prepare for the real test.
Using it is absolutely not enough to be approved with good grades.
Too expensive for what it offers.
