Features perfect installation easy

The delivery was fast and very satisfactory. Of course I can only evaluate the product after one season.

Everything great

Is not installed yet

Following a dispute over the delivery of the SVB product, the difference has been positively settled and I thank them

Excellent product. A bit expensive

Installation is easily feasible even for laypeople with basic knowledge. The quality is - as usual with Sterling products - excellent! We recommend!

Wir haben es schon mehr Jahren und sind sehr zufrieden.

Product installed on RM1060 with 2 100Ah Lithium batteries. Each time the engine is started, the alternator is called upon to produce a suitable load. I have seen up to 60A load for a 115A alternator. The Sterling alternately charges the engine battery with the two service batteries. Fully charging service batteries is faster than before.
Too bad the control box is so expensive. So I use the front panel LEDs to see what the Sterling is doing.
If at least we could know the dialog protocol of the interface.

Alright, you're welcome.

Emergency order following a breakdown, by satellite communication during the transatlantic race. Product delivered to the stopover on time, excellent service.

Did the device on a Hitachi 80A Lima and AGM batteries with 525Ah installed. The charging current is now significantly higher, the rated current of the Lima (80A) can never be achieved, probably due to the temperatures or the somewhat enthusiastic performance of the Lima. When choosing the place of installation is to be considered - protected from moisture - air circulation needed for cooling Positive - functional - easy installation - 2. Output for starter battery (thus eliminating separation diodes, etc. and associated voltage drops) - supplied temperature sensors for Lima and battery for optimal thermal control - Choice of different battery types - LED indicators on the device Negative - no indication of preferred mounting position. Since small fans blow air through the unit and due to the cooling fins, an upright position with air intake at the bottom is certainly the best way to maximize natural cooling. to benefit - fuses between Lima and charger are required. These are apparently pure fire protection and designed to be high enough so that they do not accidentally trip; because this would possibly mean the death of the Lima ...

Just erstveebebaut, only a successful test run and still no endurance test. Works, however, user manual has become much better

Device is compact, easy connection, you can pull the German translation from the Internet, that's what you do anyway, you get information about different products. Positive is that you do not have to intervene in the Lima. The only difficulty was finding a place. The prism test still follows.

The installation is not optimal, because the installation instructions are only an English translation, only the color sketch is very helpful. As not thought out is to notice that the screws of the cover with screwed on device are only badly accessible. Some are at the side of the device. As the function is during the season, it will turn out

The delivery took several weeks, without me being informed. Asked several times by phone. Each promised recalls never took place. With every demand there were excuses instead of excuses, like "I do not know anything about your repeated calls, I was on vacation, ... the first day there, ..., I'm busy with the matter for the first time, ... white not what my colleagues promised, ... I did not promise them anything ... etc.
