Whole-home backup
When WAPA drops, Powerwall picks the load up fast enough that most people only notice because the neighbours went dark.
What we carry
Two lines. Both installed by us.
Tesla Powerwall for whole-home backup, and the SRNE range of inverters and lithium batteries. Pick a line below — everything on this page is supplied, sized and commissioned by our own crew.
Tesla
Powerwall 3
When the grid goes, your house does not.
One unit, one app, Tesla's warranty. It holds what your panels made during the day, runs the house on it through an outage, and switches over fast enough that most appliances never notice.

What it does
Storm Watch
Tesla watches the weather. When a storm is tracking toward the territory, your battery charges itself to full automatically.
Time-Based Control
The system decides when to pull from the battery and when to pull from the grid, so you use as little WAPA power as the setup allows.
You can watch it work
The Tesla app shows what the panels are making, what the house is using and what is left in the battery, live.
Storm Watch, how it pairs with panels, why a grid-tied array alone goes dark with WAPA — the full Powerwall page covers all of it.
Authorised dealer
The gear behind the system.
Hybrid inverters, off-grid inverters, lithium batteries and commercial storage — 20 US-market models across four families, in stock at the Bovoni showroom. Every one links to SRNE for the full datasheet.

01 — 6 models
Residential Hybrid Inverters
One box that runs your panels, charges your battery and keeps the house on when WAPA drops. This is the family most homes here end up on.
02 — 7 models
Residential Off-Grid Inverters
For places the grid never reached, or where you would rather it did not matter. Panels and batteries only — no WAPA connection required.
03 — 6 models
Energy Storage Systems
Lithium iron phosphate batteries, from a single wall unit up to a rack. Stack them as your load grows instead of buying the whole thing on day one.
04 — 1 model
C&I Storage Inverters
Three-phase storage for hotels, warehouses, marinas and anything running a serious load. Pairs with the cabinet batteries above into a microgrid.
Not seeing it? SRNE builds more than we stock — charge controllers, RV kits, sizes we do not keep on the shelf. Tell us the model and we will price it and bring it in.
Which one is for you
Nobody buys a model number.
People call us about a bill, not a battery. So the honest answer is that the right box depends on what your house actually runs — how many AC units, whether there is a well pump, what happens at 7pm when everything comes on at once.
Broadly: Powerwall is the premium, hands-off route — one unit, one app, Tesla’s warranty. SRNE is where you go when you want more capacity for the money, an off-grid setup, or a three-phase system for a business.
Send us a WAPA bill and we will tell you which one we would put in, and why.
