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.

We’ve bought this inverter along with the panels (Canadian Solar). Our system is small, and this Sunny Boy fits it well. The shipment was fast and so far our solar project is going great.

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.

What do solar inverters do?

A1 SolarStore

The main purpose of inverters is to convert direct current (DC) electricity into altering current (AC) electricity which is used to power most appliances.

How do you maintain an inverter?

A1 SolarStore

It is recommended to wipe down your inverter when it gets dusty and to change the air intake filters, but it is best to call a technician if you are unsure of your skills.

Jess

Where should I install my inverter?

A1 SolarStore

Solar inverters best operate in shaded cool areas and are sensitive to overheating, so we recommend keeping them away from sunlight.
