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. This is achieved, for exam­ple, through the use of spe­cial ASIC chips that com­bine the func­tions of var­i­ous com­po­nents and thus bring greater reli­a­bil­i­ty. More­over, we focus on the qual­i­ty of our com­po­nents: when­ev­er pos­si­ble, we use high­ly reli­able auto­mo­tive qual­i­fied com­po­nents of par­tic­u­lar­ly high grade.

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.

Module frame as cooling fin

By means of our unique high-fre­quen­cy tech­nol­o­gy, we were able to minia­tur­ize our invert­er to a size that fits nice­ly into the frame of the PV mod­ule. Thanks to the inverter’s flat sur­face, the frame acts as a cool­ing fin.

When installing the invert­er on the mount­ing struc­ture, the ther­mal con­nec­tion to the rail can sup­port the product’s inher­ent cool­ing mechanism.
