to last

With a reduced num­ber of com­po­nents and its unique ther­mal man­age­ment, the Solar­na­tive Pow­er Stick is per­haps the most reli­able and durable micro-invet­er in the market.

Reduced component failures

The Solar­na­tive Pow­er Stick micro-invert­er is built for unprece­dent­ed reli­a­bil­i­ty. Because each com­po­nent has a cer­tain prob­a­bil­i­ty of fail­ure, prod­uct fail­ure rates are close­ly linked to the num­ber of com­po­nents in the prod­uct. There­fore, our goal was to reduce the com­po­nent count dras­ti­cal­ly. Com­pared to com­peti­tors, we only use half the num­ber of com­po­nents in our micro-invert­er. We are able to do so, because of our high degree of chip inte­gra­tion (chips are more reli­able than dis­crete com­po­nents) in two pro­pri­etary ASIC chips. More­over, we focus on the qual­i­ty of our com­po­nents: when­ev­er pos­si­ble, we use high­ly reli­able auto­mo­tive qual­i­fied com­po­nents of par­tic­u­lar­ly high quality.

Relaxed remote access

While we are doing every­thing pos­si­ble to avoid prob­lems and fail­ures, we want to make life easy for installers in the unlike­ly event that some­thing goes wrong. There­fore, our sys­tem can be mon­i­tored and main­tained remote­ly. All soft­ware set­tings can be con­fig­ured over-the-air, and reg­u­lar firmware updates ensure opti­mal performance.

Unique thermal management

The fail­ure rates of most elec­tron­ic com­po­nents increase expo­nen­tial­ly with a ris­ing tem­per­a­ture. Vice ver­sa, a tem­per­a­ture reduc­tion of 10 °C leads to a dou­bling of life­time. Know­ing this cor­re­la­tion, we pushed the ther­mal design of our micro-invert­er to the lim­its: every lit­tle fea­ture is designed to reduce tem­per­a­ture inside the invert­er and to facil­i­tate the heat flow out of the device. With its char­ac­ter­is­tic lin­ear shape and alu­minum hous­ing our invert­er is designed for almost per­fect heat dissipation.

Biggest possible cooling fin

By means of our pro­pri­etary high-fre­quen­cy tech­nol­o­gy, we were able to minia­tur­ize our invert­er to a size that fits nice­ly into the mount­ing rails or into the frame of the PV mod­ule. Thanks to the inverter’s flat sur­face, the rail or frame the invert­er is attached to acts as cool­ing fin. This helps reduce the device tem­per­a­ture by 20–30 °C, there­by increas­ing the prod­uct life time by a fac­tor of 4–8!
