Do you provide any warranty or guarantee on the batteries you sell?

Yes, we stand behind the quality of our batteries. Energy Solutions offers warranties or guarantees on our products to ensure customer satisfaction. The specific warranty terms may vary depending on the battery type and brand.

Can I get assistance in selecting the right battery for my specific needs?

Absolutely! At Energy Solutions, we have knowledgeable staff ready to assist you in choosing the right battery for your requirements. Whether it's for a car, boat, solar power system, or any other application, we can provide expert guidance to ensure you get the best battery solution.


Can the EasyGrid be kept outside?

Yes, the Zinc powder coated steel enclosure is weatherproof, however many clients choose to house the unit in an outbuilding.

How many solar panels can I have connected?

Standard for all our EasyGrids is 4kW of solar panels. You can increase the size of this solar array by upgrading the EasyGrid.

Can I add solar at a later date?

Yes, the EasyGrid is pre-wired and ready to accept up to a 4kw solar array, this can be added when this best suits you.

Can I add a wind turbine as well as solar panels?

Yes. All of the EasyGrids can be upgraded to include the dump load and flight controller wired inside the unit, so your wind turbine is all ready to connect on site.

Can I connect an EasyGrid to my existing generator?

Yes, if you already have an auto-start generator that is a suitable size you can use this with the EasyGrid.  

I own a 3 phase generator.an I use this for the EasyGrid?

Yes , you can buy an EasyGrid upgrade which allows 3 phase generators to be connected.

Do I have to use a generator?

No, not necessarily. If you have enough renewable energy sources and can get a good return from these in comparison to your loads, it is possible to be able to run the system without the use of a generator.

Do you (Energy Solutions) install the whole system?

We can give you a quotation for installing and commissioning your system, however as the system is so simple customers can have a local qualified electrician install it.

How long will it take to install?

Installation is very quick, and can be completed inside of a day.

Is the EasyGrid noisy?

The EasyGrid unit itself is completely silent.

How often will my generator run?

This all depends on how frequent your peak loads are and the use within the property. The EasyGrid will only ever run the generator when the loads go above the inverter capacity or the batteries are depleted to 50% discharge.

Will an EasyGrid system start my generator during the middle of the night?

No, the EasyGrid will run off battery power if loads are low at night, so you will have silent power during the night.

Technical Support

Cable Conductor Size & Current Ratings

Conductor Requirements for ISO 10133 and ISO 13297

This appendix is reproduced from Annex 'A' (normative) of both ISO 10133 and 13297. Both ISOs are supporting Standards to the Recreational Directive. The use of these recommendations can be used to demonstrate compliance to this Directive.

Current Ratings

The table gives allowable continuous current ratings in amperes determined for an ambient temperature of 30°C and the minimum number of strands for conductors.


Conductor current ratings may be interpolated for cross sectional areas between those shown in the Table.

* Conductors with at least a Type A stranding shall be used for general wiring of craft. Conductors with Type B stranding shall be used for any wiring where frequent flexing is involved during use.


De-rating reductions for temperature and building are cumulative where applicable. Bundling reduction factors are not normally considered necessary for DC cables in small craft.

Volt Drop Calculations

For information, (extra low voltage DC only) the volt drop on load may be calculated by using the following formula:


E = Volts drop in volts

S = The conductor cross-section area in square millimetres

I = The load current in amperes

L = The total length, in metres, of conductor from the positive power source Connection to the electrical device and back to the negative source connection.

Metric Cable Size to AWG Conversion Tables

State of Charge

The following table will allow conversion of the readings obtained to an estimate of state of charge. The table is good for the batteries at 25 deg. C (77 deg F) that have been at rest for 3 hours or more. If the batteries are at a lower temperature you can expect lower voltage readings
