SMA Sunny Tripower CORE1 50 kW String Inverter

We purchased this inverter from A1solarstore four months ago for our parking complex and since we’ve promised them a review, here it is. Overall, we are satisfied with the delivery and performance. The installation indeed was simpler than we anticipated. Our system is only 40 kW and the inverter handles it well. It is somewhat loud, but honestly, it’s not much of a problem for us. One of our employees can manage it though his smartphone, but so far there was simply no need for it.

SMA Sunny Boy Inverter 3kw SB-3.0-1SP-US-41

I was searching for solar companies online and got quotes from several of them. I evaluated them not just based on their price, but also how much information those people giving me the quotes could give me about why they were choosing that system. I decided to go with A1 Solar by my impressions of how organized they were. I had another company that I was looking at who failed to get back to me in a timely manner several times, and so I eliminated them.

Hi, how does it deal with shading.

A1 SolarStore

Good day. Better than most inverters: it has OptiTrac Global Peak shade tolerant MPP tracking. It is possible to add power optimizers to improve the performance of problematic panels.
