DIY and techy guy been studying solar for decades but never jumped in. Inherited 24 Trinasolar TSM-290PA14 panels and 4 Deka 12-Volt 1,005-AMP Farm Equipment Battery (flooded lead acid) for 48V. Need a charge controller and pure sine wave inverter and some sort of combiner boxes to tie it all together. Keeping cost low is critical. I can split and only use 10-12 panels if necessary for starters and put the rest on a Grid-tie system next year when I have the money to hire an electrician for the tie-in and buy micro-inverters. Looking at the eco-worthy 3500W (4300W max DC input) or if I could find a better one where I can use all the panels without more than double the cost. Would pay for a submittable engineering plan for permitting.

Best Solar Design Expert at your service! Dear Client, I can provide you charge controller and pure sine wave inverter and some sort of combiner After going through your project details, I am happy to inform you that these are an exact match with my skillset and experience I have read and understood your requirements and could do it for you in the least time and utmost superior quality. I have experience in inverter for Off-Grid solar and could design it for you as per your requirements. I am having more than 15 years of experience in PCB Design, Circuit Design, Circuit simulation, IOT products development and building electronic products. The expertise of mine is in the following fields: 1. IOT sensors interfacing – Pressure, Temperature, Moisture, PH etc. 2. Microcontrollers- ESP32, STM32, STM8S, RL78 etc. 3. GSM, GPS, GPRS 4. Micro-inverters, DC input, 48V, TSM-290PA14 5. Solar Products- Charger, Deck, Lamp, Energy After reading your project details, I have certain queries and suggestions: 1. What will be ambient temperature of this product? 2. What are the mechanical constraints to be taken care of? 3. What are the standards that the product would be complying to? Please try to answer these questions based on which I would be providing free of cost consultation. Please message me so that I can formulate a success plan for this project. Waiting for your reply, Regards Hari Mohan Engineering for one is a magic for others

Hi, I'm Sitav, an experienced Energy Engineer with a Master Degree majoring in Solar Engineering. I have 5+ years of experience in the solar PV field being involved in 40+ solar projects (rooftop, utility-scale, off-grid and hybrid). As you may notice in my profile portfoilio, I've been involved in the whole process of several solar projects- from load study, system design, battery modelling, creating electrical diagrams, simulation, costing to installation & commissioning, and documentation. I'm an expert in applicable software (PVsyst, PVSOL, AutoCAD, SketchUp, Helioscope etc.). I'm also well versed with the relevant International standards for design and safety. I'm certain you will benefit from my experience in this field. I have also had my Master thesis published in a journal, so I can easily fulfill your requirements. Looking forward to working with you on this exciting project.
