About this Gig
Will your backup power actually last when the grid goes down? Don't risk buying the wrong equipment. Get an exact, data-driven solar battery sizing analysis to determine your true home run time and required inverter capacity.
As an energy storage specialist, I provide an expert solar design framework that eliminates guesswork. I calculate your exact surge and continuous power loads to deliver a precise battery backup sizing report, ensuring your system runs flawlessly when you need it most.
What You Get:
- Exact solar battery sizing & total capacity requirements (kWh)
- Detailed battery run time report based on your critical loads
- Precise inverter capacity calculation (Surge vs. Continuous rating)
- Recommended battery depth of discharge (DoD) and chemistry analysis
- Compatible equipment recommendations (Victron, Growatt, Sol-Ark, etc.)
Why Work With Me?
- Focused heavily on precise, math-backed battery backup sizing.
- Clear, easy-to-understand charts detailing what appliances you can run.
- Prevents costly mistakes like overloading your inverter or draining batteries.
Get a bulletproof expert solar design before you buy your hardware.

FAQ
1. Do I need to be a technical expert to use your service?
Not at all. I'm an engineer who speaks plain English. Just tell me what appliances you want to run during an outage (fridge? lights? AC? well pump?) and for how many hours. I'll do all the math.
2. Can you size batteries for Tesla Powerwall, EG4, or other brands?
Yes. I work with any battery chemistry, Lithium (LiFePO4), Lead Acid, AGM, Tesla, LG Chem, Enphase, Sol-Ark, EG4, and generic brands. Just tell me which one you're considering.
3. Will this work for off-grid homes too?
Absolutely. Off-grid, grid-tied with backup, and hybrid systems , I calculate battery sizing for all three. Just tell me your situation.
4. What information do you need from me?
Very simple: (1) Your daily electric usage (from a utility bill OR a list of appliances), (2) How many hours of backup you want, (3) Your budget if you have one.
5. I don't have a utility bill yet, can you still help?
Yes. Send me a list of appliances you want to run (e.g., "refrigerator, 4 LED lights, TV, phone charger") and I'll estimate the load professionally.
6. Do you include inverter sizing as well?
Yes, always. An inverter that's too small will trip. One that's too big wastes money. I calculate the right inverter size matched to your battery bank.
8. Can you help if I already have solar panels and just want to add batteries later?
Yes, that's very common. I will calculate battery sizing for retrofits to existing solar systems. Just tell me your current inverter and panel specs if you know them.
9. Do you handle permits or utility applications?
This gig is for battery sizing and backup time only. But I offer permit-ready drawings and SLDs in a separate gig — just ask me.
10. What if I order and then need changes?
I include revisions
